Hi again, After otrs has been setup with ldap backend, reading from the manual, now it's time for authenticate them.. I have added this lines to Config.pm but it's not working... ################ LDAP AUTH ##################### $Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP'; $Self->{'AuthModule::LDAP::Host'} = 'domain.net'; $Self->{'AuthModule::LDAP::BaseDN'} = 'OU=domain,DC=domain,DC=net'; $Self->{'AuthModule::LDAP::UID'} = 'uid'; $Self->{'AuthModule::LDAP::SearchUserDN'} = 'CN=Israel Garcia Alvarez,OU=Sistemes,OU=Usuaris Roureda,OU=BIBM,DC=bibm,DC=net'; $Self->{'AuthModule::LDAP::SearchUserPw'} = 'Password-:)'; # in case you want to add always one filter to each ldap query, use # this option. e. g. AlwaysFilter => '(mail=*)' or AlwaysFilter => '(objectclass=user)' $Self->{'AuthModule::LDAP::AlwaysFilter'} = 'uid'; # in case you want to add a suffix to each login name, then # you can use this option. e. g. user just want to use user but # in your ldap directory exists user@domain. # $Self->{'AuthModule::LDAP::UserSuffix'} = '@domain.com'; # Net::LDAP new params (if needed - for more info see perldoc Net::LDAP) $Self->{'AuthModule::LDAP::Params'} = { port => 389, timeout => 120, async => 0, version => 3, }; ############################################ Otrs are not able to authenticate any user... Am I missing something in the setup to allow users (customers and agents) to login to our Otrs? Also, is possible to authenticate ldap and local-database users? Thanks much!!!!!!!!!! regards, Israel.
