I did this in the ACLManager product.  (Available on zope.org; requires
the DatabaseAPI product.)  It creates pseudo-users that have the roles
matching the group assignment for a directory.  Groups are assigned
locally by someone with central authority.

Unfortunately it's over a year old.  It might be useful as a reference.

One other approach is to override the __local_roles__ attribute with a
callable class instance that computes roles based on groups.  The
drawback (and a very big drawback indeed) is that to maintain
compatibility with everything that uses local roles, __local_roles__()
has to return the roles for all users, not just the current user.

Perhaps the problem should be solved by changing the security policy,
which is actually a standard thing to do.
