Configuring mod_auth_vas authentication directive with "require group" fails to work. The other options such as "require user", "require valid-user" and "require container" all seem to work. QAS is installed but is not joined to the Active Directory domain.
This will not work when you have not joined QAS to the domain as mod_auth_vas is not capable of determining group memberships. This requires the group processing which is done by QAS.
Join the unix machine to the Active Directory domain.
