Hello, I say so because I have browsed the forum, read three times the doc and cannot understand the following behaviour: .- LDAP authentication for agents works OK against Active Directory. .- Whenever try to use the same AD to authenticate customers I get the following error at /var/log/messages: Aug 13 22:07:06 localhost OTRS-CGI-10[30969]: [Notice][Kernel::System::CustomerAuth::DB::Auth] CustomerUser: No auth record in 'customer_user' for 'maripmar' (REMOTE_ADDR: 10.31.33.236) First I thought that I wasn't setting up properly the customer data backend with AD, but then I misconfigured on purpose the LDAP connection to the AD (I mean, I typed wrong the user that I am using to connect when authenticating Agents)... but I didn't get a LDAP binding error, so I suppose that OTRS doesn't take care of configuration options for customer authenticating... and keep ion using Database authentication... Is this a bug or am I doing anything wrong? Please find attached the Defaults.pm file... Thanks in advance and best regards M.A.
