Hi guys. Maybe you should have a look at:
- matrix.org - decentralized, distributed and federated chat protocol with many bridges (gitter, irc, slack etc)
- taiga.io - one of the best project management out there
- nextcloud - file sharing and more
- nextcloud - with collabora/only office/etherpad for collaborative doc editing.
You could have all of those self hosted with ldap support to have all those services accessible with just one set of credentials. I'm hosting thos services, and more with https://disroot.org project, so I could help you setup your instance of you want, or you could use our services.
