    Sun 7310 IDMU/SMB/NFS Woes

    atopher
      We have had a 7310 box for a couple of years and I have never got to grips with NFS & CIFS permissions.

      I have given up on the Identity mapping as it seems to cause nothing but a headache unless you have everything in place on both sides. I.e. as soon as a user that is not on the NFS client drops a file on an NFS share, the NFS client simply cannot read the ACLs + plus a load of other permission issues I have been unable to sort out.

      Finally had a bit of time to look into this and downloaded the simulator.

      So the plan now is to keep things simple:
      - NFS client mounts the share over NFSv3, so no ACLs to deal with. This may cause issues later down the line but I need to ensure that NFS clients can access the files. v3 is the easiest way to achieve this.
      - SMB client mounts the share as usual
      - I will use IDMU to get unix UID's and GID's from AD for the users and groups I know require to access from both protocols.

      Simple eh?

      Not so :-( It seems that as soon as I enable IDMU on the device, I am unable to access the share over SMB - it asks for a username and password. Switch IDMU off and return to ID mapping, and I can access the share (but then I ma back to square one). I know that the Unix IDs for the group and user are OK - they are showing up in the Mappings tab.

      There is the following error in the system log though:
           
      smbd[1425] alert adt_set_user: Invalid argument

      Can anyone advise what might be causing this error?

      Any help/advice on the subject appreciated, I have been tearing my hair out over this for a while!

          Am back to sorting out ID mapping now and have asked a similar NFSv4 question in the Solaris forum.

          Still, any pointers as to how to successfully configure ID mapping for NFS/SMB would very useful.

            Hey,

            we are using Windows 2008 R2 ADS with SFU/IDMU.

            Our 7310 connects via LDAP to the Global Catalog to fetch any PosixAccounts/GroupAccounts.

              Wow thanks for this, only just checked back as am not receiving notifications.

              Will give it a shot on the test box later today.

              Thanks, Chris
