CIFS share root access / force user samba equivalent

JBD_LONGUSERNAME — Thu, 05 Jun 2025 06:07:36 GMT

Hello everybody,

I'm using NetApp Release 7.3.5.1.

I'm using ldap authentication and unix permissions only, no windows acl. I would like to access my CIFS shares with a "super user" that can access everything.

For example, here is a directory listed through NFS :

drwxrws--- 10 root Vmv 12288 Feb 22 12:18 Vmv

The permissions are 2770, you have to be in the Vmv group to access it, through NFS or CIFS.

This is the corresponding cifs share :

filer> cifs shares Vmv

Name Mount Point Description

---- ----------- -----------

Vmv /vol/myvolume/Vmv

... forcegroup=Vmv

Vmv{g} / Full Control

Samba offers a "force user" directive which is exactly what I need :

force user (S)

This specifies a UNIX user name that will be assigned as the default user for all users connecting to this service. This is useful for sharing files. You should also use it carefully as using it

incorrectly can cause security problems.

This user name only gets used once a connection is established. Thus clients still need to connect as a valid user and supply a valid password. Once connected, all file operations will be

performed as the "forced user", no matter what username the client connected as. This can be very useful.

Is there a NetApp equivalent ? If not, is there a way to achieve what I want ? I could add myself to the Vmv group, but I could have some files under the Vmv directory not accessible to the Vmv group. And I have got thousands of shares with different groups. Basically, I just want a "super user" cifs access 😃

Regards,

Jean-Baptiste

there is no force user kind of functionality, but you can use -forcegroup" functionality for CIFS access. set the necessary permissions to the UNIX group on the directory or volume. configure that group as "-forcegroup" on the share.
