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.
After about a year of using Keycloak for some #dayjob side projects, I literally just stood it up in my homelab.
It does have a learning curve, but it supports OIDC and SAML - those two should get most internal services covered.
Back end can federate with AD or LDAP - for the real stinkers who refuse to support SSO. (Looking at you Netbox)
