   - `samlEndpoint`: string. The SAML endpoint.

   - `samlCertificate`: string. The base64 encoded SAML certificate.
   - `enabled`: boolean. Determines if the provider is enabled or not.
+  - `enableAuthorization`: boolean: Determines if the plugin sets permissions for the user. If false, the user will start with no permissions and an administrator will add permissions. The permissions of existing users will not be rewritten on subsequent logins.
   - `enableAllFolders`: boolean. Determines if the client logging in is allowed access to all folders.
   - `enabledFolders`: array of strings. If `enableAllFolders` is set to false, then this will be used to determine what folders the users who log in through this provider are allowed to use.
+  - `roles`: array of strings. This validates the SAML response against the `Role` attribute. If a user has any of these roles, then the user is authenticated. Leave blank to disable role checking.
+  - `adminRoles`: array of strings. This uses SAML response's `Role` attributes. If a user has any of these roles, then the user is an admin. Leave blank to disable (default is to not enable admin permissions).
+  - `enableFolderRoles`: boolean. Determines if role-based folder access should be used.
+  - `folderRoleMapping`: object in the format "role": string and "folders": array of strings. The user with this role will have access to the following folders if `enableFolderRoles` is enabled. To get the IDs of the folders, GET the `/Library/MediaFolders` URL with an API key. Look for the `Id` attribute.

+- POST `Unregister/username`: This "unregisters" a user from SSO. A JSON-formatted string must be posted with the new authentication provider.

 ## Limitations
 
 There is no GUI to sign in. You have to make it yourself! The buttons should redirect to something like this: [https://myjellyfin.example.com/sso/SAML/p/clientid](https://myjellyfin.example.com/sso/SAML/p/clientid) replacing `clientid` with the provider client ID and `SAML` with the auth scheme (either `SAML` or `OID`).
