We use LDAP authentication for our moodle system.
The mobile app guideline indicates 'browser window' should be selected for 'Type of Login' when using SSO with LDAP.
While we use LDAP for authentication I didnt think it was considered 'SSO' as its not used to authenticate other applications so we have left the default option of 'via the app' for authentication.
Should I consider this SSO and user the 'browser option' rather than 'via the app' for authentication?
We have a lot of 500 errors related to login/token.php and index.php so I was wondering if 'via the app' for authentication was the reason.
thanks
Environment:
Moodle 3.11.5

SSO authentication method
If your site uses a SSO authentication method (CAS, Shibboleth, LDAP SSO, OAuth...), then select via a browser window or via an embedded browser for 'Type of login' (typeoflogin) in 'Mobile authentication' in the Site administration. (This setting is provided for older pre-Moodle 3.2 sites via the Moodle Mobile additional features plugin.)
