L.S. I would like to use my existing AD/ldap for Customer Authentication. In the documentation I cannot find a way to achieve this. I Configured the following (from ZZZAuto.pm): $Self->{'SecureMode'} = 1; $Self->{'SystemID'} = 13; $Self->{'FQDN'} = 'pb001-n01.osb.edunet'; $Self->{'AdminEmail'} = 'otrsadministrator@openschoolgemeenschapbijlmer.nl'; $Self->{'Organization'} = 'Open Schoolgemeenschap Bijlmer'; $Self->{'DefaultLanguage'} = 'nl'; $Self->{'LogModule'} = 'Kernel::System::Log::File'; $Self->{'LogModule::LogFile'} = 'C:/OTRS/otrs/var/log/otrs.log'; delete $Self->{'SendmailModule::Port'}; delete $Self->{'Package::RepositoryList'}; $Self->{'Customer::AuthModule'} = 'Kernel::System::CustomerAuth::LDAP'; $Self->{'Customer::AuthModule::LDAP::Host'} = 'ldap.openschoolgemeenschapbijlmer.nl'; $Self->{'Customer::AuthModule::LDAP::BaseDN'} = 'dc=osb,dc=edunet'; $Self->{'Customer::AuthModule::LDAP::UID'} = 'sAMAccountName'; $Self->{'Customer::AuthModule::LDAP::SearchUserDN'} = 'cn=otrsldap,ou=users,dc=osb,dc=edunet'; $Self->{'Customer::AuthModule::LDAP::SearchUserPw'} = 'xxxxxxxx'; $Self->{'1'} = 1; A similar setup works for our ELO (moodle) so I know that the ldapauthenticationsetup works. (password crippled in this mail) With this configuration I expected that everybody that gets authenticated via AD can login as customer. I cannot get any userid to properly login on http://localhost/otrs/customer.pl Not even when I create a customer with the same credentials as in AD via the admin module. I am obviously missing something. Can someone please shed a light on this for me please? Thanks in advance, Peter Berkhout.
