CIFS share ignores group permissions

Hi all,

I've a shared volume (not qtree) with cifs mode.

I've created a AD group (LABWIN\FabricaRetiradesLectura) that has one member: LABWIN\imatges

DISC1> wcc -s LABWIN\imatges

(NT - UNIX) account name(s):  (LABWIN\imatges - imatges)

        ***************

        UNIX uid = 245

        user is a member of group program (100)

        user is a member of group group (50)

        user is a member of group program (100)

        NT membership

                LABWIN\imatges

                LABWIN\Usuarios de Acceso Web remoto de Windows SBS

                LABWIN\Usuarios de fax de Windows SBS

                LABWIN\Windows SBS SharePoint_MembersGroup

                LABWIN\Usuarios del vínculo de Windows SBS

                LABWIN\FabricaRetiradesLectura

                LABWIN\Usuarios del dominio

                BUILTIN\Users

        User is also a member of Everyone, Network Users,

        Authenticated Users

        ***************

DISC1> fsecurity show /vol/FABRICA/proves

[/vol/FABRICA/proves - Directory (inum 161953)]

  Security style: NTFS

  Effective style: NTFS

  DOS attributes: 0x0030 (---AD---)

  Unix security:

    uid: 0 (root)

    gid: 1 (daemon)

    mode: 0777 (rwxrwxrwx)

  NTFS security descriptor:

    Owner: BUILTIN\Administrators

    Group: LABWIN\Usuarios del dominio

    DACL:

      Allow - LABWIN\FabricaRetiradesLectura - 0x001f01ff (Full Control) - OI|CI

      Allow - LABWIN\Administrador - 0x001f01ff (Full Control) - OI|CI

Although the folder has NTFS permissions to this group, and the user is a member of the group, I can't access the folder:

Sectrace says this:

Access allowed because requested permission is granted on parent directory.

    - Access allowed by an explicit access control entry.

Access denied because requested permission is not granted on file or directory.

    - Access allowed by share-level ACL.

    - Access denied because the requested permissions are not granted by the access control entries.

Am I doing something wrong?

Thank you!

Re: CIFS share ignores group permissions

Hey all!

Thanks

Re: CIFS share ignores group permissions

I was just about to create a post on this very issue.  I am even having issues with users or groups that i add to the cifs not showing up at all.  Im not much on the command line side so i used oncommand to create the share and added our network admins group and all was fine.  I then added an individual user to this share and they show in the oncommand console but the user does not have access. I connected using computer management in windows to look at the share permissions and the users is not listed.

Re: CIFS share ignores group permissions

Please try the following steps:-

  • Execute 'wcc -s <ntname> -x' command on the filer.

                                       OR

  • Execute 'wcc -x' command on the filer. (wcc -x will invalidate the entire credential cache so be informed that this may result in an increased traffic from filer to AD for a little while till WAFL Credential Cache (wcc) is re populated)
  • If it asks for confirmation, gives 'yes'.

Now, try accessing the volume from the client.

Please let me know if it works.

(For more info, try 'man wcc' on the filer)

Re: CIFS share ignores group permissions

Hi,

     We experience the same issue. Is this resolve? Appreciate if we can get answer how this issue resolve. Thank you.

Re: CIFS share ignores group permissions

I tried what Ashok suggested, but it didn't fix the problem.  We have the same issue, any help would be appreciated. This seems like a fairly basic functionality that shouldn't be this difficult to solve.  We had no problem with our old NetApp, it had this functionality out of the box.

Re: CIFS share ignores group permissions

I ran into the same problem after granting a domain group access to a CIFS share. It was only after checking the AD Group Type that I found the root cause -- it was set to Distribution and not to Security.  After changing the Group Type to Security, I was able to access the CIFS share using a user account from within the group.  Hopefully, this solves some of the issues out there.
