[Samba] Problems with Unix Permissions and ACLs

[Adam Luchjenbroers]

System is RHEL3 with Samba 3.0.0.

I have a share that is configured to be accessible only to a specific group
(Test Admin).

[delta]
comment = Testing
path = /var/test
valid users = @"TEST/App - Test Admin"
admin users = @"TEST/App - Test Admin"
writable = yes

Via the NT security dialog, file permissions are mapping fine but all
directories have empty ACLs (no permissions for any). File permissions in
question have been checked.

Despite this lack of permissions, directories can be entered and browsed,
however files cannot be created. In addition, no file may be written to,
though reading works fine.
