Desktop Client with Authentik OAuth - dnightbane - 2025-02-24
Hello!
I recently installed Jellyfin, and have connected it with Authentik for SSO. This works great for the browser however when I try to login with SSO on the desktop client I just get a black screen after hitting "Sign in with SSO" (shown below). Is there something I'm missing in the setup or is LDAP the only option (This would require setting a local password on the OAUTH user so not necessarily the ideal scenario)?

Which server version are you running and what version of Jellyfin Media Player? Also, are you using a reverse proxy?
RE: Desktop Client with Authentik OAuth - dnightbane - 2025-02-25
Apologies, that would be useful information to include.
Jellyfin Version: 10.10.6 (docker)
Jellyfin Player Version: 1.11.1 (Windows)
Reverse Proxy: Nginx (docker)

Can you go over this walkthrough another forum user wrote?
https://forum.jellyfin.org/t-jellyfin-authentik-duo-2fa-solution-tutorial
Double check your setup lines up with their walkthrough?
And can you provide your Nginx config? Censor the domain.

Definitely a good guide for LDAP with 2FA, thank you!
That post also made me realize my initial post was missing a few more details, apologies about that.
The authentik flow for this domain is set to OAUTH with plex.tv (Figured this would be an easy way to allow my users to choose whichever they want without having to maintain multiple credentials) so when a user goes to https://jellyfin.domain.com they are instantly redirected to authentik which pops a login for plex.tv. This works as expected in the browser but I suspect may not be a supported configuration for the clients so LDAP and different credentials may be the route I need to go.
My nginx config
server {
listen 443 ssl;
http2 on;
server_name jellyfin.domain.com;
include /etc/nginx/conf.d/https.conf;
## The default
client_max_body_size is 1M, this might not be enough for some posters, etc.client_max_body_size 20M;

The Nginx config looks fine. But I don't think your current flow will work with a lot of clients so, as you said, you will probably need to go the LDAP route.
RE: Desktop Client with Authentik OAuth - Duvel - 2025-02-26
The clients capabilities are really the bottleneck in using OAUTH/SSO pluggin. IMO Its not usable in the actual state because of this and should be disregarded.
Everyone that use or have users using different clients than web (which is most probably the case of everyone), can only use the LDAP pluggin if they want proper working SSO.... And LDAP is much, MUCH harder to setup.
It would be nice if the Jellyfin team could emphasis on the importance to implement SSO OAUTH correctly in the clients. We are in 2025... I just dont get how client devs still dont realize that its not a "nice-to-have" anymore. Its rather a must-have to not say an obligation.
