[Samba] Permissions issue 3.0.2a

[Nick THOMPSON]

Hi,

I have two users (one is me), connecting to the same directory tree on a
Solaris box, for simplicity using smbclient for Samba 3.0.2a. In this
tree, group permissions are set to rwx for a group that we are both in.
I own some dirs, my colleague owns others.

If I log in, I can put a file in any directory in the tree. If my
colleague logs in, he can only write to directories that he owns.
Directly on Solaris (and via linux) using NFS we can both write to all
directories.

The logs just say permission denied. Any ideas what could be wrong?

Many thanks,
Nick.
