Good morning, list, I have a problem, but my knowledge with MySQL and Perl is very limited. I try to explain what happens. When I have a local customer backend, my customer can create a new ticket on the customer interface, all is good (the ticket is created on the agent interface, and mail is send to this agent to aware there are a new ticket). When I configure Active directory authentication for my customer, I see all active directory users on the Agent interface, the customer can login on the Interface web (that is good). But when the customer create a new ticket and click to summit he have this screen with this error : Erreur: Can't get ArticleID from INSERT! (I Have the same message in apache Log) . He need to close his Internet Browser and re logon to see his Ticket. All the same the ticket is created for the Agent (on the Agent interface)in the correct Queue; but the agents not receive an email to aware them there are a new ticket in this file. I thinks perhaps is a problem with OTRS (or active Directory) which need to create an entry in MySQL database. Anybody have an ideas? (thanks in advance), I hope my mail is clear (sorry for my English) King regards Sébastien Bory Administrateur réseaux
