I have a lot of different services which I self host for me and my family like:
- PeerTube
- Lemmy
- Mastodon
- Synology NAS
- TTRSS
- NextCloud
- Matrix
- HomeAssistant
- etc.
Right now every family member needs to create a user on each of those services and have a different password on them, which is OK when you use a Password Manager, but most of my extended family members don’t. And they often forget their password and stop using the service because they can’t figure out how to reset the password with each and every service.
I would like to try to consolidate all of it with a Single Sign-On (SSO) solution but It’s not obvious to me if there is one which is not overly over engineered for hundreds of thousands of users but small and lightweight, perhaps even easy to set up.
I tried OpenLDAP but Jesus that was very involved.
What I would dearly like is an SSO system that can also act as a drop-in replacement for Kerberos. Existing krb5 servers (on Linux) are ancient, quirky, and underdocumented, but kerberos is so useful at a CLI level. I’ve always maintained separate LDAP & Kerberos instances, and the thing stopping me from moving to something more modern is that I’m holding out for that kerberos feature…
