What is Jellyfin​

Jellyfin is a free and open source media management and streaming platform for movies, TV shows, and music.

-- https://jellyfin.org

note

Jellyfin does not have any native external authentication support as of the writing of this page.

note

Currently, there are two plugins for Jellyfin that provide external authentication, an OIDC plugin and an LDAP plugin.

caution

An LDAP outpost must be deployed to use the Jellyfin LDAP plugin

Preparation​

The following placeholders will be used:

  • jellyfin.company is the FQDN of the Jellyfin install.
  • authentik.company is the FQDN of the authentik install.
  • ldap.company the FQDN of the LDAP outpost.
  • dc=company,dc=com the Base DN of the LDAP outpost.
  • ldap_bind_user the username of the desired LDAP Bind User

LDAP Configuration​

authentik Configuration​

No additional authentik configuration needs to be configured. Follow the LDAP outpost instructions to create an LDAP outpost and configure access via the outpost

Jellyfin configuration​

  1. If you don't have one already, create an LDAP bind user before starting these steps.
    • Ideally, this user doesn't have any permissions other than the ability to view other users. However, some functions do require an account with permissions.
    • This user must be part of the group that is specified in the "Search group" in the LDAP outpost.
  2. Navigate to your Jellyfin installation and log in with the admin account or currently configured local admin.
  3. Open the Administrator dashboard and go to the Plugins section.
  4. Click Catalog at the top of the page, and locate the "LDAP Authentication Plugin"
  5. Install the plugin. You may need to restart Jellyfin to finish installation.
  6. Once finished, navigate back to the plugins section of the admin dashboard, click the 3 dots on the "LDAP-Auth Plugin" card, and click settings.
  7. Configure the LDAP Settings as follows:
    • LDAP Server: ldap.company
    • LDAP Port: 636
    • Secure LDAP: Checked
    • StartTLS: Unchecked
    • Skip SSL/TLS Verification:
      • If using a certificate issued by a certificate authority, Jellyfin trusts, leave this unchecked.
      • If you're using a self-signed certificate, check this box.
    • Allow password change: Unchecked
      • Since authentik already has a frontend for password resets, it's not necessary to include this in Jellyfin, especially since it requires bind user to have privileges.
    • Password Reset URL: Empty
    • LDAP Bind User: Set this to a user you want to bind to in authentik. By default, the path will be ou=users,dc=company,dc=com so the LDAP Bind user will be cn=ldap_bind_user,ou=users,dc=company,dc=com.
    • LDAP Bind User Password: The Password of the user. If using a Service account, this is the token.
    • LDAP Base DN for Searches: the base DN for LDAP queries. To query all users, set this to dc=company,dc=com.
      • You can specify an OU if you divide your users up into different OUs and only want to query a specific OU.

At this point, click Save and Test LDAP Server Settings. If the settings are correct, you will see: Connect(Success); Bind(Success); Base Search (Found XY Entities)

  • LDAP User Filter: This is used to a user filter on what users are allowed to login. This must be set
    • To allow all users: (objectClass=user)
    • To only allow users in a specific group: (memberOf=cn=jellyfin_users,ou=groups,dc=company,dc=com)
    • Good Docs on LDAP Filters: atlassian.com
  • LDAP Admin Base DN: All the users in this DN are automatically set as admins.
    • This can be left blank. Admins can be set manually outside this filter
  • LDAP Admin Filter: Similar to the user filter, but every matched user is set as admin.
    • This can be left blank. Admins can be set manually outside this filter

At this point, click Save and Test LDAP Filter Settings. If the settings are correct, you will see: Found X user(s), Y admin(s)

  • LDAP Attributes: uid, cn, mail, displayName
  • Enable case Insensitive Username: Checked

At this point, enter a username and click Save Search Attribute Settings and Query User. If the settings are correct, you will see: Found User: cn=test,ou=users,dc=company,dc=com

  • Enabled User Creation: Checked
  • LDAP Name Attribute: cn
  • LDAP Password Attribute: userPassword
  • Library Access: Set this according to desired library access
  1. Click "Save"
  2. Logout, and login with a LDAP user. Username must be used, logging in with email will not work.

OIDC Configuration​

authentik Configuration​

Provider Settings

In authentik under Providers, create an OAuth2/OpenID Provider with these settings:

  • Name: jellyfin
  • Redirect URI: https://jellyfin.company/sso/OID/redirect/authentik

Everything else is up to you, just make sure to grab the client ID and the client secret!

note

The last part of the URI is the name you use when making the provider in Jellyfin so make sure they are the same.

Application Settings

Create an application that uses jellyfin provider. Optionally apply access restrictions to the application.

Set the launch URL to https://jellyfin.company/sso/OID/start/authentik

Jellyfin Configuration​

  1. Navigate to your Jellyfin installation and log in with the admin account or currently configured local admin.
  2. Open the Administrator dashboard and go to the Plugins section.
  3. Then click the Repositories section at the top and add the below repository with the name of SSO-Auth
https://raw.githubusercontent.com/9p4/jellyfin-plugin-sso/manifest-release/manifest.json

  1. Click the Catalog tab on top and install the SSO-Auth with the most recent version.

  2. Restart the Jellyfin server.

  4. Click the SSO-Auth plugin.

  5. Fill out the Add / Update Provider Configuration:

    • Name of OID Provider: authentik
    • OID Endpoint: https://authentik.company/application/o/jellyfin/.well-known/openid-configuration
    • OpenID Client ID: ClientID from provider
    • OID Secret: Client Secret from provider
    • Enabled: CHECKED
    • Enable Authorization by Plugin: CHECKED

  6. If you want to use the role claim then also fill out these:

    • Roles: roles to look for when authorizing access (should be done through authentik instead)
    • Admin Roles: roles to look for when giving admin privilege
    • Role Claim: groups

  7. Hit Save at the bottom.

  8. On the left side now click the General under dashboard and go to Branding.

  9. In the login disclaimer put this code and making sure to change the url at the top:

<form action="https://jellyfin.company/sso/OID/start/authentik">
  <button class="raised block emby-button button-submit">
    Sign in with SSO
  </button>
</form>
  1. In the Custom CSS code also add this:
a.raised.emby-button {
    padding:0.9em 1em;
    color: inherit !important;
}

.disclaimerContainer{
    display: block;
}
  1. Click Save at the bottom & restart the server.
  2. When you are signed out you should now see a Sign in with SSO button.
note

If you have problems check your logs which are under the Administration -> Dashboard then "logs" and will be near the bottom (most likely) with Jellyfin.Plugin.SSO_Auth. as the start of the lines you are looking for.
