I have a tree for LDAP authentication where web-based application bind on
to authenticate users.

I'm looking for a way to auhtorize only valid users to log on a
workstation with the Client 32. These users are members of a group. I do
not need access to filesystem, just authorize members of a specific group
to log.

I want to use the client32. Is there a way to do it? Maybe with an
NMAS method?
