[otrs] LDAP: Agent-Login works, but Customer-Login does not. Problem with AuthModule::LDAP::AlwaysFilter

[Stefan Michael Guenther]

Hello,

I'm currently trying to setup the LDAP authentication for both agents and customers. While the agents can login without a problem, the customers can't. We checked the logfiles and found out, that OTRS uses "AuthModule::LDAP::AlwaysFilter" for agents and customers, although we have defined "Customer::AuthModule::LDAP::AlwaysFilter". Here are the relevant lines from the config file, did we make a type or misunderstood something in the configuration? BTW, we are using version 3.1.9

sub Load {
my $Self = shift;

$Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP';
$Self->{'AuthModule::LDAP::Host'} = '192.168.10.5';
$Self->{'AuthModule::LDAP::BaseDN'} = 'o=in-put';
$Self->{'AuthModule::LDAP::UID'} = 'uid';
$Self->{'AuthModule::LDAP::SearchUserDN'} = 'cn=otrsuser,o=in-put';
$Self->{'AuthModule::LDAP::SearchUserPw'} = 'xxxxxxx';
$Self->{'AuthModule::LDAP::AlwaysFilter'} = '(memberOf=cn=OTRS,ou=Gruppen,o=IN-PUT)';
$Self->{'AuthModule::LDAP::Params'} = { port => 389,timeout => 120,async => 0, version => 3,};
$Self->{'AuthSyncModule'} = 'Kernel::System::Auth::Sync::LDAP';
$Self->{'AuthSyncModule::LDAP::Host'} = '192.168.10.5';
$Self->{'AuthSyncModule::LDAP::BaseDN'} = 'o=in-put';
$Self->{'AuthSyncModule::LDAP::UID'} = 'uid';
$Self->{'AuthSyncModule::LDAP::SearchUserDN'} = 'cn=otrsuser,o=in-put';
$Self->{'AuthSyncModule::LDAP::SearchUserPw'} = 'xxxxx';
$Self->{'AuthSyncModule::LDAP::UserSyncMap'} = { UserFirstname => 'givenName',UserLastname => 'sn',UserEmail => 'mail', };
$Self->{'AuthSyncModule::LDAP::UserSyncInitialGroups'} = ['users',];

$Self->{'Customer::AuthModule'} = 'Kernel::System::Auth::LDAP';
$Self->{'Customer::AuthModule::LDAP::Host'} = '192.168.10.5';
$Self->{'Customer::AuthModule::LDAP::BaseDN'} = 'ou=user,o=in-put';
$Self->{'Customer::AuthModule::LDAP::UID'} = 'uid';
$Self->{'Customer::AuthModule::LDAP::SearchUserDN'} = 'cn=otrsuser,o=in-put';
$Self->{'Customer::AuthModule::LDAP::SearchUserPw'} = 'xxxxx';
$Self->{'Customer::AuthModule::LDAP::AlwaysFilter'} = '(sn=*)';
$Self->{'Customer::AuthModule::LDAP::Params'} = {port => 389, timeout => 120, async => 0, version => 3,};
$Self->{'Customer::AuthSyncModule'} = 'Kernel::System::Auth::Sync::LDAP';
$Self->{'Customer::AuthSyncModule::LDAP::Host'} = '192.168.10.5';
$Self->{'Customer::AuthSyncModule::LDAP::BaseDN'} = 'o=in-put';
$Self->{'Customer::AuthSyncModule::LDAP::UID'} = 'uid';
$Self->{'Customer::AuthSyncModule::LDAP::SearchUserDN'} = 'cn=otrsuser,o=in-put';
$Self->{'Customer::AuthSyncModule::LDAP::SearchUserPw'} = 'xxxxx';
$Self->{'Customer::AuthSyncModule::LDAP::UserSyncMap'} = {UserFirstname => 'givenName', UserLastname => 'sn',UserEmail => 'mail', };
$Self->{'Customer::AuthSyncModule::LDAP::UserSyncInitialGroups'} = ['customers',];


Thanks for any hints or suggestions,

Stefan

There is no CustomerAuthSync Module

You probably don't want this? $Self->{'Customer::AuthModule::LDAP::AlwaysFilter'} = '(sn=*)';

You have no CustomerUser information.

This is how I made mine work. You can adapt as needed.........

Hi,

> There is no CustomerAuthSync Module

hm, now OTRS accepts the login name and the passwords, but since there isn't a corresponding account in OTRS, the customer can not login.
If there isn't a snyc for customers, how should this work?
