When I follow the built-in documentation for LDAP authentication it will show an error when a user tries to log in, even though the “'''Test Credentials'''” shows as successful. The error is “'''LDAP: Attribute missing: ‘uid’'''“ which I assume is linked to the “'''Username Attribute field (Required)'''” which I have configured as sAMAccountName as detailed in the documentation. I can see that authentication is working because if I enter an incorrect password or account it indicates that its incorrect. I am not using SAML as this is not an option at the moment. I have also tried all 3 options for LDAP (OpenLDAP, AD & Other) but it makes no difference.
