Hi, I managed to use HTTPBasicAuth for Customer-Login. But when I open the customer.pl the system says "Panic! No UserData". I understand that the User can't be in the DB, but I don't know how to tell it should create a new user if it's unknown (like UserSyncLDAPMap for LDAP). Can I use UserSyncLDAPMap for that? (If so, how!?) I want to have a Single-Sign on solution for our windows-users. OTRS 2.2.1 runs on a Fedora 7 machine... Thanks for your support! Best regards, David
