Include/exclude filter is not working on subwikis

Using the ldap_user_group and ldap_exclude_group configuration parameters works as expected on the main wiki.

But on a subwiki, in case a user fails to login (because is either on the exclude side, or not on the include list), the process is redirected to the global login. In this case, the user will be able to login if  the main wiki configurations are accepting it.
