[otrs] Auth in 2 groups

Hi list, My techs are in 2 Active Directory groups. I whant each tech can access to otrs application. In Config.pm I have this line : $Self->{'AuthModule::LDAP::GroupDN'} = 'cn=grp1,ou=MyOU,dc=domain,dc=local'; What is the syntax to had 2 groups. I have try this but don't works: $Self->{'AuthModule::LDAP::GroupDN'} = '(|(cn=grp1)(cn=grp2)),ou=MyOU,dc=domain,dc=local'; I want that only these 2 groups can access to the tech interface. Anyone have an idea ?
