      Description

      when running sync_users.php to update moodle db from ldap directory (Active Directory in my case) existing user details are updated but new users are not and the php script finishes with "!!! Error Writing to Database !!!" Enabling debugging and rerunning the script gives the additional error
      "Notice undefined property: stdClass::$username in /pathtoWeb/auth/ldap/auth.php on line 848

      The issue is discussed here http://moodle.org/mod/forum/discuss.php?d=203600

      Note: noticed the problem earlier but wasn't a show stopper for me at the time so earlier versions of moodle may be also affected
