Group verification not supported for Active Directory

[viharm]

phpLDAPauth's feature for authorising users from select groups (even if authenticated), does not exist in the current AD functionality. This is because AD stores user-group relationship in the user's entry (unlike OpenLDAP, which stores it in the group).

This needs to be enabled.

See https://samjlevy.com/use-php-and-ldap-to-get-a-users-group-membership-including-the-primary-group/ for such functionality until this is added to phpLDAPauth
