I don't really need all of the auditing and compliance features this solution seems to currently offer- I just need a simple SSO proxy. If some one wants to build that, it could be a huge help for small non-commercial self-hosters like me.
What's important is that you follow the releases. Read the logs after you update. Something the configuration format changes.
And there are some rough edges. But those are OIDC related. The actual authentication part is much older and stable.
I've only had issues with a configuration NOT allowing me to sign in. Which I appreciate. I rather have a bug that blocks me vs one that allows me.
And they're pretty responsive on discord.
