Samba & AD

[uxbod]

Hi,

i have got Samba talking to our AD server and wbinfo -u and -g return domain information fine. i have created a samba share, for arguments, called smbtest and here is the entry from smb.conf :-

[smbtest]
comment = Samba AD Test
path = /samba
valid users = @"sambatest_rw"
read only = No
create mask = 2660

the permissions on the directory /samba are as follows :-

drwxr-x--- root smbtest /samba

now the issue, or misunderstanding, i am having is that I have created a groupmap between the unix group smbtest and the AD group sambatest_rw using :-

net groupmap add sid="S-1-5-21-1659004503-113007714-1177238915-2190" type=d ntgroup="sambatest_rw" unixgroup="smbtest"

but when trying to map to the share it is saying that I dont have enough permissions. my windows user id exists in the sambatest_rw group but the mapping does not seem to work as i should be able to get into the directory using the smbtest=>sambatest groupmap relationship.

Is this right?

TIA
