Private IRC server with local user accounts?
(alien.top)
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
For Example
We welcome posts that include suggestions for good self-hosted alternatives to popular online services, how they are better, or how they give back control of your data. Also include hints and tips for less technical readers.
Useful Lists
Ergo, formerly oragono, supports LDAP and possibly SAML. This is not something I have set up, but I have hosted a public ergo server before.
Good luck.
