[Dovecot] restricting shared folders access

Hi all,

I have a dovecot setup with virtual users and a passwd-file passdb.  All 
users have the same uid and gid.  Recently I got my public folders 
working using namespaces and they work great.  However, now I'm trying 
to share a folder between a limited number of users and so far I failed 
to get it working.  Symlinks aren't an option because users need to be 
able to create subfolders of the shared folder so I'm trying to do it 
with namespaces but I'm not sure how to restrict access to a limited 
number of users.

I tried doing it with groups.  I made sure that the shared folder's 
group is set to 'staff'  and the mode is 070, I also changed the group 
of a few virtual users to 'staff'.  However, when I try accessing the 
shared folder I get a permission denied error (although the user is in 
the staff group).

Can someone please recommend the best way to do this?  Should I look 
into ACL's?

Many thanks,


Andrew.
