Dear Friends, I have installed OTRS on OpenSUSE Linux distro. I have tried to performe auth via LDAP. I have configured the "Config.pm" file. The system "/var/log/messages" files gives the following message: Mar 17 10:49:27 marine OTRS-CGI-10[4687]: [Notice][Kernel::System::Auth::LDAP::Auth] User: saydin (uid=saydin,ou=### <Deleted for security> ###) authentication ok (REMOTE_ADDR: ::1). Mar 17 10:49:28 marine OTRS-CGI-10[4687]: [Notice][Kernel::System::User::GetUserData] Panic! No UserData for user: 'saydin'!!! As understood from the message and from the documents about "Panic! No UserData", I should configure "Config.pm" similar to following way. ############################# $Self->{UserSyncLDAPGroups} = [ 'users', ]; $Self->{UserSyncLDAPMap} = { # DB -> LDAP id => 'uidNumber', login => 'uid', first_name => 'cn', last_name => 'gecos', valid_id => 'uidNumber', }; ################# Our LDAP DB information for me as follows; dn: uid=saydin,ou= <Deleted for security> uid: saydin cn: selcuk han aydin objectClass: account objectClass: posixAccount objectClass: top objectClass: shadowAccount loginRShell: /bin/rbash homeRDirectory: /home/user shadowLastChange: 6445 loginShell: /bin/bash uidNumber: 17332 gidNumber: 10044 homeDirectory: /home502/saydin gecos: selcuk han aydin major: bidb minor: adm type: 1 Would you please help me how configure "Congif.pm" for the correct mapping.
