Your problem is not related to Plone or PlonePAS.

Basically if you are using PAS and you want to authenticate with a
user that is not defined in PAS user folder in the context you are
trying to log in but in a upper level user folder, then you might not
be able to login if that user folder is not a PAS one in some setups.

Why? Because what happens is:

 1. Page requires authentication
 2. The PAS closer to your location issues a challenge
 3. PAS extracts the credentials and tries to authenticate, but fails
    because the user is defined in a upper level user folder.
 4. Now, if the upper level user folder is a standard user folder, not
    PAS, it can't extract the credentials from the request because
    'its too late' in the request to do that. However if it is a PAS
    then it can because of the way PAS was designed.

There is a thread from a couple months ago where I explained this in
better detail.
