Samba alternative group share problem

Hello,

I have a user, "reg"  which is a member of "users" but also a member of the groups "svn", "web-dev" and a couple of other groups.

When logged on as this user on my server I can get to a directory called ".svn" but not when using the same user through a samba share.

Below are the details of my setup  and what happens when when I list from the samba share vs. on the server as the same user and the samba config files. Both the client and the server are Linux computers, OS = openSUSE 11.0 (client) & 11.2 (server). The uid of "reg" is the same on the server and client.

The share in question is "[data]" which you can see from the smb.conf file is a very simple config.

The share is mounted on the client with a normal cifs mount.

As you can see from line 48 below that from the client I get a "permission denied" which is not the case from the server (line 67).

Client cifs-mount version is 3.4.5
Server samba version is 3.4.2


Any help appreciated.
