I'm trying to set up an NFS path where all clients get squashed to a single UID

The normal export doesn't work, as my NFS clients are Linux 2.6 with real uid/gids sent /vol/vol1 -sec=sys,rw,anon=100 In this case, only ROOT client access get squashed to uid 100.

Instead, here's what I tried: /vol/vol1 -sec=none,rw,anon=100

Unfortunately, my Redhat Linux client (2.6.9-42.ELsmp) refuses to mount Mounting NFS filesystems: mount: 192.168.1.10:/vol/vol1 failed, security flavor not supported

Packet traces show the Linux system sends the MNT request with Flavor AUTH_UNIX, and the NetApp replies OK-Flavor:AUTH_NULL along with the appropriate supplemental fsid file handles.

Only, Linux is 'smart' and refuses.

I also don't have any server side control over GID either.
