Migration from Confluence and LDAP configuration with users with dot in CN

after migration and LDAP setup whether this duplicates come from incorrect LDAP setup and which user is correct

I suppose ideally it should be made more explicit in the user profile that it’s an LDAP user but the standard profile is missing some extension points in the UI to allow the LDAP authenticator to insert information like these.
