Package: samba
Version: 2:3.3.2-1
Severity: normal


I have a samba pdc that uses an ldapsam backend. Everything seems to work,
with the expection of the following share:

        path = /store
        hide unreadable = yes
        csc policy = disable
        force group = +Power Users
        inherit acls = true
        volume = STORE
        create mask = 0666
        directory mask = 0777

When I connect to this share from either smbclient or Windows on a domain
workstation, the connection is denied and samba logs "make_connection:
connection to store denied due to security descriptor." If I comment out
"force group", connections succeed.

The users I tested with were members of "power users", but I also tested
with just "force group = username" (the name of the actual user), which
should have had no effect for that user as his primary gid was already his
own usergroup. But the connection was denied even so.

The [global] section of my smb.conf reads as follows:
