User creation and saving profiles broken for authentication providers

[hukoeth]

I've just installed Jellyfin nightly on my Raspi 4 (armhf, debian package) and found the following issues:

• When trying to create a new user (setting is enabled in LDAP), error "Login failed" is displayed
• When saving profiles (in admin dashboard as well as logged in as the user) I also get "Login Failed". Changes are still saved

If you need more information please let me know

Confirmed jellyfin/jellyfin-plugin-ldapauth#1 on Debian nightly.

From my testing, seems to have been caused by #2363.

Logs when this happens:

Mar 08 15:19:50 jf1.i.net jellyfin[2095]: [15:19:50] [ERR] Error processing request: [10.x.0.y] Invalid user or password entered.

I would expect this to check the auth provider and that create the user, but instead it just dies.

As a test, I'm reverting #2363 to see if this improves things.

It's not #2363 but something else. Needs further investigation CC @Bond-009 @dkanada.

For now this isn't really a blocker for 10.5.0 - @hukoeth as a workaround, you could create the user then manually set its authentication provider to the LDAP one in order to auth there.

Hmm I assumed it would be my pull request.

I tried this but the login fails with this error:

Looks like the issue was introduced in #2146 - trying to find the ideal solution.

Does anyone have a working Jellyfin + LDAP setup working? Which version of Jellyfin and which version of LDAP plug work together? Thanks. Are there any updates on this issue? Where can I read more about it?
