Hi, I have just set up LDAP (Active Directory) back-end for customer users on OTRS. I can login fine using my credentials from active directory, the problem I am experiencing is that when using the LDAP back-end trying to create a new ticket from the customer.pl front-end results in long delays, in excess of a minute. These delays are experienced after clicking on the New Ticket button before the form appears and also on each refresh of the form when the drop-down lists are selected. Switching to the database back-end but maintaining the LDAP authentication fixes the problem. Using database back-end and authentication fixes the problem. There are no long delays on logging in or searching for customer users from the admin interface, so it does not seem to be any direct link with the speed of the LDAP server. I have not been able to find anything relating to this problem with google. I am using OTRS 2.4.4 with ITSM 1.3.1, although I experienced the same problem with earlier versions of OTRS 2.4.x. Has anybody experienced something similar. Any suggestions of where I should look to resolve this problem? Thanks, Mischa
