I'm a long-time user of Trac. It's a Python based client-server application, which means you run it on the server, and the "clients" need nothing but a web browser to access it: Example screenshot from one of my projects / Android clients (click images for larger variants) It certainly matches your requirements: Creation of tickets: Sure.

I agree with Customizer's suggestion of Redmine. Our team has been using it for years and it's worked out great for us. Just so you know, you can go to Digital Ocean and quickly spin up Redmine with their one-click install. Might be quicker than installing on your own server for testing.

LaTeX is a document preparation system. Strictly speaking, LaTeX is a markup language built on top of the TeX typesetting system; more generally “LaTeX” can mean a set of tools built around the typesetting system.

Multi user (simultaneous access to different notes) — This isn't provided by Org itself, but because Org documents are plain text, you can use generic tools such as SSH or version control systems (e.g., ...

You search a database front-end. Wiki I guess a Wiki software should solve your needs. This way you can share and cross-reference your knowledge and the results of your investigations Compared to a relational database this is very fuzzy, but creating a DB schema for your data types is hard work and would take too much time if you are new to databases. ...

KeePass does fine with multiple users: http://keepass.info/help/base/multiuser.html - the 'Syncronize' option is what you want. There's even an advanced option that automatically takes the 'syncronize' option when saving. You just have to make sure that only people who need the database have access to the share and it should work fine (it does for me).

(I want it for university associations) You will need to do a fair bit of customizing to get the functionality you want from the standard CMSs, I believe, although that would of course be possible. However, I think Elgg would be able to give you most of the functionality you want. It is a "social networking engine", aimed in particular at "...
