Day 1:
Training period commences.
My mouse laser sensor doesn't work.
Solution: Use this mouse to log in to your system.
Open the company portal.
Connect to vpn.
Enter username password.
Create a ticket for mouse replacement.
Done.
Day 3
I bring my own mouse.
Confiscated at security.
Becomes a security violation.
Day 9
I get a call from helpdesk.
Agent- what is the problem?
Me- my mouse is not working.
Agent- why?
Me- what do you mean? Something is wrong with the sensor.
Agent- clean the sensor.
Disconnects call.
Marks ticket as resolved.
Me- WTF just happened!
Naturally, I escalate the issue.
Day 15
Level 2 Agent- what happened? Why have you escalated the issue?
Me- I need a mouse, waiting since 2 weeks.
Him- No mouse is available
Me- you don't have a single spare mouse available in an office with 5000 PC users?
Him- no they're out of stock.
Me- when will it be back in stock?
Him- we will 'soon' launch a tender for quotations from sellers.
Me- time?
Him- 1 week.
Day 34
I email the head of supplies for the city office. Next day I get a used super small mouse, which doesn't have a left button. Anyways, I've given up hope now.
Day 45
I become a master at keyboard shortcuts.
Finish my training.
Get transferred to another city.
No mouse till date.
Surprisingly, this was one of the top recruiters in my country. Never knew, MNCs can be so so inefficient for such simple tasks.
Start-ups are way better in this regard. Latest tech, small community, minimal bureaucracy and a lot of respect and things to learn.15 -
Taking IT classes in college. The school bought us all lynda and office365 accounts but we can't use them because the classroom's network has been severed from the Active Directory server that holds our credentials. Because "hackers." (The non-IT classrooms don't have this problem, but they also don't need lynda accounts. What gives?)
So, I got bored, and irritated, so I decided to see just how secure the classroom really was.
It wasn't.
So I created a text file with the following rant and put it on the desktop of the "locked" admin account. Cheers. :)
1. don't make a show of "beefing up security" because that only makes people curious.
I'm referring of course to isolating the network. This wouldn't be a problem except:
2. don't restrict the good guys. only the bad guys.
I can't access resources for THIS CLASS that I use in THIS CLASS. That's a hassle.
It also gives me legitimate motivation to try to break your security.
3. don't secure it if you don't care. that is ALSO a hassle.
I know you don't care because you left secure boot off, no BIOS password, and nothing
stopping someone from using a different OS with fewer restrictions, or USB tethering,
or some sort malware, probably, in addition to security practices that are
wildly inconsistent, which leads me to the final and largest grievance:
4. don't give admin priveledges to an account without a password.
seriously. why would you do this? I don't understand.
you at least bothered to secure the accounts that don't even matter,
albeit with weak and publicly known passwords (that are the same on all machines),
but then you went and left the LEAST secure account with the MOST priveledges?
I could understand if it were just a single-user machine. Auto login as admin.
Lots of people do that and have a reason for it. But... no. I just... why?
anyway, don't worry, all I did was install python so I could play with scripting
during class. if that bothers you, trust me, you have much bigger problems.
I mean you no malice. just trying to help.
For real. Don't kick me out of school for being helpful. That would be unproductive.
Plus, maybe I'd be a good candidate for your cybersec track. haven't decided yet.
-- a guy who isn't very good at this and didn't have to be
have a nice day <3
oh, and I fixed the clock. you're welcome.2 -
I used to work in a small agency that did websites and Phonegap apps, and the senior developer was awful.
He had over a decade of experience, but it was the same year of experience over and over again. His PHP was full of bad practices:
- He'd never used an MVC framework at all, and was resistant to the idea, claiming he was too busy. Instead he did everything as PHP pages
- He didn't know how to use includes, and would instead duplicate the database connection settings. In EVERY SINGLE FILE.
- He routinely stored passwords in plain text until I pretty much forced him to use the new PHP password hashing API
- He sent login details as query strings in a GET request
- He couldn't use version control, and he couldn't deploy applications using anything other than FTP4 -
Not as much of a rant as a share of my exasperation you might breathe a bit more heavily out your nose at.
My work has dealt out new laptops to devs. Such shiny, very wow. They're also famously easy to use.
.
.
.
My arse.
.
.
.
I got the laptop, transferred the necessary files and settings over, then got to work. Delivered ticket i, delivered ticket j, delivered the tests (tests first *cough*) then delivered Mr Bullet to Mr Foot.
Day 4 of using the temporary passwords support gave me I thought it was time to get with department policy and change my myriad passwords to a single one. Maybe it's not as secure but oh hell, would having a single sign-on have saved me from this.
I went for my new machine's password first because why not? It's the one I'll use the most, and I definitely won't forget it. I didn't. (I didn't.) I plopped in my memorable password, including special characters, caps, and numbers, again (carefully typed) in the second password field, then nearly confirmed. Curiosity, you bastard.
There's a key icon by the password field and I still had milk teeth left to chew any and all new features with.
Naturally I click on it. I'm greeted by a window showing me a password generating tool. So many features, options for choosing length, character types, and tons of others but thinking back on it, I only remember those two. I had a cheeky peek at the different passwords generated by it, including playing with the length slider. My curiosity sated, I closed that window and confirmed that my password was in.
You probably know where this is going. I say probably to give room for those of you like me who certifiably. did. not.
Time to test my new password.
*Smacks the power button to log off*
Time to put it in (ooer)
*Smacks in the password*
I N C O R R E C T L O G I N D E T A I L S.
Whoops, typo probably.
Do it again.
I N C O R R E C T L O G I N D E T A I L S.
No u.
Try again.
I N C O R R E C T L O G I N D E T A I L S.
Try my previous password.
Well, SUCCESS... but actually, no.
Tried the previous previous password.

Ahh fuck, I can't believe I've done this, but going to support is for pussies. I'll put this by the rest of the fire, I can work on my old laptop.
Day starts getting late, gotta go swimming soonish. Should probably solve the problem. Cue a whole 40 minutes trying my 15 or so different passwords and their permutations because oh heck I hope it's one of them.
I talk to a colleague because by now the "days since last incident" counter has been reset.
"Hello there Ryan, would you kindly go on a voyage with me that I may retrace my steps and perhaps discover the source of this mystery?"
"A man chooses, a slave obeys. I choose... lmao ye sure m8, but I'm driving"
We went straight for the password generator, then the length slider, because who doesn't love sliding a slidey boi. Soon as we moved it my upside down frown turned back around. Down in the 'new password' and the 'confirm new password' IT WAS FUCKING AUTOCOMPLETING. The slidey boi was changing the number of asterisks in both bars as we moved it. Mystery solved, password generator arrested, shit's still fucked.
Bite the bullet, call support.
"Hi, I need my password resetting. I dun goofed"
*details tech support needs*
*It can be sorted but the tech is ages away*
Gotta be punctual for swimming, got two whole lengths to do and a sauna to sit in.
"I'm off soon, can it happen tomorrow?"
"Yeah no problem someone will be down in the morning."
Next day. Friday. 3 hours later, still no contact. Go to support room myself.
The guy really tries, goes through everything he can, gets informed that he needs a code from Derek. Where's Derek? Ah shet. He's on holiday.
There goes my weekend (looong weekend, bank holiday plus day flexi-time) where I could have shown off to my girlfriend the quality at which this laptop can play all our favourite animé, and probably get remind by her that my personal laptop has an i2350u with integrated graphics.
TODAY. (Part is unrelated, but still, ugh.)
Go to work. Ten minutes away realise I forgot my door pass.
Bollocks.
Go get a temporary pass (of shame).
Go to clock in. My fob was with my REAL pass.
What the wank.
Get to my desk, nobody notices my shame. I'm thirsty. I'll have the bottle from my drawer. But wait, what's this? No key that usually lives with my pass? Can't even unlock it?
No thanks.
Support might be able to cheer me up. Support is now for manly men too.
*Knock knock*
"Me again"
"Yeah give it here, I've got the code"
He fixes it, I reset my pass, sensibly change my other passwords.
Or I would, if the internet would work.
It connects, but no traffic? Ryan from earlier helps, we solve it after a while.
My passwords are now sorted, machine is okay, crisis resolved.
*THE END*
If you skipped the whole thing and were expecting a tl;dr, you just lost the game.
Otherwise, I absolve you of having lost the game.

Whelp. I started making a very simple website with a single-page design, which I intended to use for managing my own personal knowledge on a particular subject matter, with some basic categorization features and a simple rich text editor for entering data. Partly as an exercise in web development, and partly due to not being happy with existing options out there. All was going well...
...and then feature creep happened. Now I have implemented support for multiple users with different access levels; user profiles; encrypted login system (and encrypted cookies that contain no sensitive data lol) and session handling according to (perceived) best practices; secure password recovery; user-management interface for admins; public, private and group-based sections with multiple categories and posts in each category that can be sorted by sort order value or drag and drop; custom user-created groups where they can give other users access to their sections; notifications; context menus for everything; post & user flagging system, moderation queue and support system; post revisions with comparison between different revisions; support for mobile devices and touch/swipe gestures to open/close menus or navigate between posts; easily extendible css themes with two different dark themes and one ugly as heck light theme; lazy loading of images in posts that won't load until you actually open them; auto-saving of posts in case of browser crash or accidental navigation away from page; plus various other small stuff like syntax highlighting for code, internal post linking, favouriting of posts, free-text filter, no-javascript mode, invitation system, secure (yeah right) image uploading, post-locking...
On my TODO-list: Comment and/or upvote system, spoiler tag, GDPR compliance (if I ever launch it haha), data-limits, a simple user action log for admins/moderators, overall improved security measures, refactor various controllers, clean up the code...
It STILL uses a single-page design, and the amount of feature requests (and bugs) added to my Trello board increases exponentially with every passing week. No other living person has seen the website yet, and at the pace I'm going, humanity will have gone through at least one major extinction event before I consider it "done" enough to show anyone.

When I was in 11th class, my school got a new setup for the school PCs. Instead of just resetting them every time they are shut down (to a state in which it contained a virus, great) and having shared files on a network drive (where everyone could delete anything), they used iServ. Apparently many schools started using that around that time, I heard many bad things about it, not only from my school.
Since school is sh*t and I had nothing better to do in computer class (they never taught us anything new anyway), I experimented with it. My main target was the storage limit. Logins on the school PCs were made with domain accounts, which also logged you in with the iServ account, then the user folder was synchronised with the iServ server. The storage limit there was given as 200MB or something of that order. To have some dummy files, I downloaded every program from portableapps.com, that was an easy way to get a lot of data without much manual effort. Then I copied that folder, which was located on the desktop, and pasted it onto the desktop. Then I took all of that and duplicated it again. And again and again and again... I watched the amount increate, 170MB, 180, 190, 200, I got a mail saying that my storage is full, 210, 220, 230, ... It just kept filling up with absolutely zero consequences.
At some point I started using the web interface to copy the files, which had even more interesting side effects: Apparently, while the server was copying huge amounts of files to itself, nobody in the entire iServ system could log in, neither on the web interface, nor on the PCs. But I didn't notice that at first, I thought just my account was busy and of course I didn't expect it to be this badly programmed that a single copy operation could lock the entire system. I was told later, but at that point the headmaster had already called in someone from the actual police, because they thought I had hacked into whatever. He basically said "don't do again pls" and left again. In the meantime, a teacher had told me to delete the files until a certain date, but he locked my account way earlier so that I couldn't even do it.
Btw, I now own a Minecraft account of which I can never change the security questions or reset the password, because the mail address doesn't exist anymore and I have no more contact to the person who gave it to me. I got that account as a price because I made the best program in a project week about Java, which greatly showed how much the computer classes helped the students learn programming: Of the ~20 students, only one other person actually had a program at the end of the challenge and it was something like hello world. I had translated a TI Basic program for approximating fractions from decimal numbers to Java.
The big irony about sending the police to me as the 1337_h4x0r: A classmate actually tried to hack into the server. He even managed to make it send a mail from someone else's account, as far as I know. And he found a way to put a file into any account, which he shortly considered to use to put a shutdown command into autostart. But of course, I must be the great hacker.3 -
So, the Network I was on was blocking every single VPN site that I could find so I could not download proton onto my computer without using some sketchy third-party site, so, being left with no options and a tiny phone data plan, I used the one possible remaining option, an online Android emulator. In the emulator running at like 180p I once again navigated to proton VPN, downloaded the windows version, and uploaded it to Firefox send. Opened send on my computer, downloaded the file, installed it, and realized my error, I need access to the VPN site to log in.
In a panic, I went to my phone ready to use what little was left of data plan for security, and was met with no signal indoors. Fuck. New plan. I found a Xfinity wifi thing, and although connecting to a public network freaked me out, I desided to go for it because fuck it. I selected the one hour free pass, logged in, and it said I already used it, what? When?, So I created a new account, logged in, logged into proton, and disconnected, and finally, I was safe.
Fuck the wifi provider for discouraging a right to a private internet and fuck the owner for allowing it. I realize how bad it was to enter my proton account over Xfinity wifi, but I was desperate and desperate times call for desperate means. I have now changed my password and have 2fa enabled.1 -
The dangers of PHP eval()
Yup. "Scary, you better make use of include instead" — I read all the time everywhere. I want to hear good case scenarios and feel safe with it.
I use the eval() method as a good resource to build custom website modules written in PHP which are stored and retrieved back from a database. I ENSURED IS SAFE AND CAN ONLY BE ALTERED THROUGH PRIVILEGED USERS. THERE. I SAID IT. You could as well develop a malicious module and share it to be used on the same application, but this application is just for my use at the moment so I don't wanna worry more or I'll become bald.
I had to take out my fear and confront it in front of you guys. If i had to count every single time somebody mentions on Stack Overflow or the comments over PHP documentation about the dangers of using eval I'd quit already.
Tell me if I'm wrong: in a safe environment and trustworthy piece of code is it OK to execute eval('?>'.$pieceOfCode); ... Right?
The reason I store code on the database is because I create/edit modules on the web editor itself.
I use my own coded layers to authenticate a privileged user: A single way to grant access to admin functions through a unique authentication tunnel granting so privileged user to access the editor or send API requests, custom htaccess rules to protect all filesystem behind the domain root path, a custom URI controller + SSL. All this should do the trick to safely use the damn eval(), is that right?!
Unless malicious code is found on the code stored prior to its evaluation.
But FFS, in such scenario, why not better fuck up the framework filesystem instead? Is one password closer than the database.
I will need therapy after this. I swear.
If 'eval is evil' (as it appears in the suggested tags for this post) how can we ensure that third party code is ever trustworthy without even looking at it? This happens already with chrome extensions, or even phone apps a long time after reaching to millions of devices.11 -
While attempting to quit smoking and after spending a full day trying to understand why the previous devs took this approach to encrypting a string and my lack of nicotine addled brain not allowing me to see that this was a “Secure”String and so uses a machine specific key (that’s why the code that worked locally wouldn’t run on production 😑) this is my rant on comments added to the helper I had to write
/// <summary>
/// If you are using this class and it's not for backward compatibility - then you probably shouldn't be using it
/// Nothing good comes from "Secure" strings
/// Further to this Secure strings are only "useful" for single user crypto as the encryption uses the login creds, transferring
/// this data to another client will result in them never being able to decrypt it
///
/// Windows uses the user's login password to generate a master key.
/// This master key is protected using the user's password and then stored along with the user's profile.
/// This master key then gets used to derive a number of other keys and it's these other keys that are used to protect the data.
///
/// This is also a broken crypto method via injection (see Hawkeye http://hawkeye.codeplex.com/) plus the string is stored in plain
/// text in memory, along with numerous other reasons not to use it.

I managed to remember some old Bitwarden (password manager service, I remember that linuxxx recommended me this one a looong time ago) credentials, so I logged in. I found an old devRant account - not my first though (I deleted it).
I've been a random lurker all this time (this is the first dev community I've been and I'm not planning to leave it until it dies), and it's good to login just to give my 2 cents.
I love you all. Seriously. I love you all with every single bit of my heart (get it?), impartially. Thanks for existing.
Here's an interrupted "caramelCase posted a new rant!"; it's actually longer but a wild guy ++'d my comment.

Okay this is my first time posting on this site. I've browsed it (definitely not in class) and the community looks beautiful, so I'm going to just kind of slide in here. Anyways this is the part where I use my caps lock button and type lots of naughty words I guess...
<rant type = 'school'>
Our programming classes are fucking DISMAL uuugh... Okay so we have four technology classes: Tech Exploration, Coding 1, Coding 2, and Intro to CS (a 'high school' level class)... So this means a fuck ton of kids in programming classes, mostly because I WANNA MAKE MINCERAFT AND BE A KEWL BOI LIKE GAME DEV BUT I'M ALSO A FUCKING IDIOT AND WILL NOT LEARN ANYTHING YAAAAAAY but that's a mood and so there's a fucking tidal wave of dumb kids in these classes. So right we're dealing with like 80 kids per class period. Sorry if I'm repeating myself but there are a FUCKTON of students. Now, we have... wait for it... ONE FUCKING TEACHER. ONE. I fucking swear this district does not give a SINGLE SHIT about possibly THE SINGLE FUCKING MOST IMPORTANT SUBJECT WHYYYYYY... Okay so the teacher is kinda overworked as fuck lol. She can't really teach eighty kids at once so she mostly gives us exercises from websites but when she can she teaches us shit herself and actually knows a good bit about her field of study. She's usually pretty grumpy, understandably, but if you ask her a good question that makes her think you can see the passion there lol. So anyways that's a mood. Now at the other school it's even worse. They have this new asshole as a teacher that knows NOTHING about ANYTHING IT IS SO FUCKING REDICULOUS OH MY UUUUUGH... THEY STILL DON'T EVEN KNOW WHAT A FUCKING LOOP IS LIKE OKAY YOU'VE BEEN TEACHING PROGRAMMING FOR A YEAR AND YOU'RE THE ONLY ONE TEACHING IT AT THAT DISTRICT SO MAYBE YOU SHOULD AT LEAST FUCKING TRY WHAT IS WRONG WITH YOU... so he just makes them do shit from a website and obviously can't do half of the shit he assigns it's so fucking sad... I swear this district is supposed to be good but maybe not for the ONE THING I WANT IT TO BE GOOD FOR. Funny story: in elementary school once I wrote down school usernames for people I didn't really know and shared them a google doc that said "you have been hacked make a more secure password buddy" etc etc and made them the owner and these dull shits report it to the principal... So I'm in the principles office... Just a fucking dumb elementary school kid lol and the principal is like hAcKiNg Is BaD yOu ShOuLd NoT dO iT and I'm like how did you know it was me... so he goes on to say some bullshit about 'digital footprint' and 'tracing' me to it... he obviously has no clue what he's saying but anyways afterwards he points to where it says last change made by MY SCHOOL ACCOUNT... HOW DULL CAN YOU FUCKING POSSIBLY BE IT WAS FROM MY ACCOUNT THAT LITERALLY PROVED THAT I DID --NOT-- 'HACK' INTO THEIR ACCOUNT YOU DUMB FUCK. Okay so basically my school is a burning pile of garbage but it's better than most apparently but it's GARBAGE MY GOD... Please fucking tell me it gets better...
okay lol that was longer than I thought it would be guess I just needed to vent... later I guess

I am just student looking for job, and got this pre interview test:
Develop an Android or iOS app with login and password input field, download button, place for image we prvided.
... reading further:
What we are looking for in the code ?
internal quality:
-consistent formatting of the source code
-clean, robust code without smells
-consistent abstractions and logical overall structure
-no cyclic dependencies
-code organized in meaningful layers
-low coupling and high cohesion
-descriptive and intention-revealing names of packages, classes, methods etc.
-single small functions that do one thing
-truly object-oriented design with proper encapsulation, sticking to DRY and SOLID principles, without procedural anti-patterns
-lots of bonus points for advanced techniques like design patterns, dependency injection, design by contract and especially unit (or even functional or integration) tests
external quality:
-the app should be fully functional, with every state, user input, boundary condition etc. taken care of (although this app is indeed very small, treat it as a part of big production-ready project)
-the app should correctly handle screen orientation changes, device resources and permissions, incoming calls, network connection issues, being pushed to the background, signing deal with the devil :D and other platform intricacies and should recover from these events gracefully
-lowest API level is not defined - use what you think is reasonable in these days
-bonus points if the app interacts with the user in an informative and helpful way
-bonus points for nice looks - use a clean, simple yet effective layout and design
... I mean really ? and they give me like 2 days ?4 -
I hate hate hate Windows. I'm forced to use it and the amount of problems is too damn high. I was able to cope with the shit but now it must be the top of the mountain. When I boot that tiny piece of sh** I get to the page where *normally* the login is.. but I just don't get a Username + Password box . The page stays blank with the default wallpaper. Why is stuff like that even happening? Not a single *solution* I found on the internet worked. FML.. going to reset that thing now5

Over the last few weeks, I've containerised the last of our "legacy" stacks, put together a working proof of concept in a mixture of DynamoDB and K8s (i.e. no servers to maintain directly), passing all our integration tests for said stack, and performed a full cost analysis with current & predicted traffic to demonstrate long term server costs can be less than half of what they are now on standard pricing (even less with reserved pricing). Documented all the above, pulled in the relevant higher ups to discuss further resources moving forward, etc. That as well as dealing with the normal day to day crud of batting the support department out the way (no, the reason Bob's API call isn't working is because he's using his password as the API key, that's not a bug, etc. etc.) and telling the sales department that no, we can't bolt a feature on by tomorrow that lets users log in via facial recognition, and that'd be a stupid idea anyway. Oh, and tracking down / fixing a particularly nasty but weird occasional bug we were getting (race hazards, gotta love 'em.)
Pretty pleased with that work, but hey, that's just my normal job - I enjoy it, and I like to think I do good work.
In the same timeframe, the other senior dev & de-facto lead when I'm not around, has... "researched" a single other authentication API we were considering using, and come to the conclusion that he doesn't want to use it, as it's a bit tricky. Meanwhile passed all the support stuff and dev stuff onto others, as he's been very busy with the above.
His full research amounts to a paragraph which, in summary, says "I'm not sure about this OAuth thing they mention."
Ok, fine, he works slowly, but whatever, not my problem. Recently however, I learn that he's paid *more than I am*. I mean... I'm not paid poorly, if anything rather above market rate for the area, so it's not like I could easily find more money elsewhere - but damn, that's galling all the same.5 -
I’m working on a new app I’m pretty excited about.
I’m taking a slightly novel (maybe 🥲) approach to an offline password manager. I’m not saying that online password managers are unreliable, I’m just saying the idea of giving a corporation all of my passwords gives me goosebumps.
Originally, I was going to make a simple “file encrypted via password” sort of thing just to get the job done. But I’ve decided to put some elbow grease into it, actually.
The elephant in the room is what happens if you forget your password? If you use the password as the encryption key, you’re boned. Nothing you can do except set up a brute-forcer and hope your CPU is stronger than your password was.
Not to mention, if you want to change your password, the entire data file will need to be re-encrypted. Not a bad thing in reality, but definitely kinda annoying.
So actually, I came up with a design that allows you to use security questions in addition to a password.
But as I was trying to come up with “good” security questions, I realized there is virtually no such thing. 99% of security question answers are one or two words long and come from data sets that have relatively small pools of answers. The name of your first crush? That’s easy, just try every common name in your country. Same thing with pet names. Ice cream flavors. Favorite fruits. Childhood cartoons. These all have data sets in the thousands at most. An old XP machine could run through all the permutations over lunch.
So instead I’ve come up with these ideas. In order from least good to most good:
1) [thinking to remove this] You can remove the question from the security question. It’s your responsibility to remember it and it displays only as “Question #1”. Maybe you can write it down or something.
2) there are 5 questions and you need to get 4 of them right. This does increase the possible permutations, but still does little against questions with simple answers. Plus, it could almost be easier to remember your password at this point.
All this made me think “why try to fix a broken system when you can improve a working system”
So instead,
3) I’ve branded my passwords as “passphrases” instead. This is because instead of a single, short, complex word, my program encourages entire sentences. Since the ability to brute force a password decreases exponentially as length increases, and it is easier to remember a phrase rather than a complicated amalgamation or letters number and symbols, a passphrase should be preferred. Sprinkling in the occasional symbol to prevent dictionary attacks will make them totally uncrackable.
In addition? You can have an unlimited number of passphrases. Forgot one? No biggie. Use your backup passphrases, then remind yourself what your original passphrase was after you log in.
All this accomplished on a system that runs entirely locally is, in my opinion, interesting. Probably it has been done before, and almost certainly it has been done better than what I will be able to make, but I’m happy I was able to think up a design I am proud of.8 -
Relatively often the OpenLDAP server (slapd) behaves a bit strange.
While it is little bit slow (I didn't do a benchmark but Active Directory seemed to be a bit faster but has other quirks is Windows only) with a small amount of users it's fine. slapd is the reference implementation of the LDAP protocol and I didn't expect it to be much better.
Some years ago slapd migrated to a different configuration style - instead of a configuration file and a required restart after every change made, it now uses an additional database for "live" configuration which also allows the deployment of multiple servers with the same configuration (I guess this is nice for larger setups). Many documentations online do not reflect the new configuration and so using the new configuration style requires some knowledge of LDAP itself.
It is possible to revert to the old file based method but the possibility might be removed by any future version - and restarts may take a little bit longer. So I guess, don't do that?
To access the configuration over the network (only using the command line on the server to edit the configuration is sometimes a bit... annoying) an additional internal user has to be created in the configuration database (while working on the local machine as root you are authenticated over a unix domain socket). I mean, I had to creat an administration user during the installation of the service but apparently this only for the main database...
The password in the configuration can be hashed as usual - but strangely it does only accept hashes of some passwords (a hashed version of "123456" is accepted but not hashes of different password, I mean what the...?) so I have to use a single plaintext password... (secure password hashing works for normal user and normal admin accounts).
But even worse are the default logging options: By default (atleast on Debian) the log level is set to DEBUG. Additionally if slapd detects optimization opportunities it writes them to the logs - at least once per connection, if not per query. Together with an application that did alot of connections and queries (this was not intendet and got fixed later) THIS RESULTED IN 32 GB LOG FILES IN ≤ 24 HOURS! - enough to fill up the disk and to crash other services (lessons learned: add more monitoring, monitoring, and monitoring and /var/log should be an extra partition). I mean logging optimization hints is certainly nice - it runs faster now (again, I did not do any benchmarks) - but ther verbosity was way too high.
The worst parts are the error messages: When entering a query string with a syntax errors, slapd returns the error code 80 without any additional text - the documentation reveals SO MUCH BETTER meaning: "other error", THIS IS SO HELPFULL... In the end I was able to find the reason why the input was rejected but in my experience the most error messages are little bit more precise.2 -
Someone earlier today posted a rant about a credit card security conference sending them account details with a plain text password in an email. The password appeared to be 1 use temporary password that the user would change on first login. Assuming one does not actually store plain text passwords, what is the downside to a single use password Vs a single use link to set a new password?1

hey, so i have recently started learning about node js and express based backend development.
can you suggest some good github repositories that showcase real life backend systems which i can use as inspiration to learn about the tech?
like for eg, i want to create a general case solution for authentication and profile management : a piece of db+api end points + models to :
- authenticate user : login/signup , session expire, o auth 2 based login/signup, multi account login, role based access, forgot password , reset password, otp login , etc
- authorise user : jwt token authentication, ip whitelisting, ssl pinning , cors, certificate based authentication , etc (
- manage user : update user profile, delete user, map services , subscriptions and transactions to user , dynamic meta properties ( which can be added/removed for a single user and not exactly part of main user profile) , etc
followed by deployment and the assoc concepts involved : deployment, clusters, load balancers, sharding ,... etc
----
these are all the buzzwords that i have heard that goes into consideration when designing a secure authentication system for a particular large scale website like linkedin or youtube. am not even sure how many of these concepts would require actual codelines and how many would require something else.
so wanted inspiration from open source content to learn about it in depth, replicate and create new better stuff if possible .
apart from that, other backend architectures like video/images storage system, or just some server for movie, social media, blog website etc would also help.2
