We use ldap for user auth, I also have a backup local user, after an upgrade from 10.1 to 11rc1 log login is possible for agents or users.The only clue I can find is in the PHP log since the upgrade I'm getting a lot of this when I attempt to login: PHP Warning: Declaration of QueueColumnListBroker:($columns, &$errors, $options = Array) should be compatible with InstrumentedList:(array $what) in C:\inetpub\wwwroot\helpdesk\include\class.queue.php on line 0 PHP Warning: Declaration of AdhocSearch:($staff) should be compatible with CustomQueue:(Staff $agent) in C:\inetpub\wwwroot\helpdesk\include\class.search.php on line 909 PHP Warning: Declaration of TeamSelectionField:() should be compatible with FormField:($path) in C:\inetpub\wwwroot\helpdesk\include\class.search.php on line 1262 PHP Warning: session_start(): Failed to read session data: user (path: C:\Windows\temp) in C:\inetpub\wwwroot\helpdesk\include\class.ostsession.php on line 86 PHP Warning: Declaration of QueueColumnListBroker:($columns, &$errors, $options = Array) should be compatible with InstrumentedList:(array $what) in C:\inetpub\wwwroot\helpdesk\include\class.queue.php on line 0 PHP Warning: Declaration of AdhocSearch:($staff) should be compatible with CustomQueue:(Staff $agent) in C:\inetpub\wwwroot\helpdesk\include\class.search.php on line 909 PHP Warning: Declaration of TeamSelectionField:() should be compatible with FormField:($path) in C:\inetpub\wwwroot\helpdesk\include\class.search.php on line 1262 PHP Warning: session_start(): Failed to read session data: user (path: C:\Windows\temp) in C:\inetpub\wwwroot\helpdesk\include\class.ostsession.php on line 86I believe this might be related to PHP 7.1, can anyone help before I have to roll back the VM?Thanks!
