Hi Cristophe, thanks for the explanation... I'll try and see if this speed-up things!

Hi Carnino, I posted in a previous thread my (almost) working Config.pm file for Agent and Customer authentication with an AD backend. Almost, because in the file there is a typo: I used somewhere UserPricipalName instead of UserPriNcipalName... (See http://lists.otrs.org/pipermail/otrs/2008-June/023522.html Customer authentication via Active Directory) If you use AD as a backend, I would suggest to use the dnsdomainname as host (fi: fiatgroup.com.local, I don't know what your AD dnsdomainname is) for redundancy (DNS roundrobin to all your DC's) and contact not the LDAP port (389 if I'm not mistaken), but the Global Catalog port: 3268 (queries should be faster).
