I am unable to change the default login from username to (main) email address.
ldap_loginname_attribute = userPrincipalName and also
ldap_loginname_attribute = mail but neither brought some change and I still could only login with name only.
Should this work or is this the wrong option? I guess I could change
loginname_format = %u to
loginname_format = %firstname.lastname@example.org in server.cfg but that should be everything but best practice…
Thanks in advance
