I care that all users store files as "nobody" on an NFS volume.
So I wanted to use the option 'sec=none'.
On NFS clients in Windows 7 Ultimate mount to "/vol/nfs2 -sec=none,rw" works fine and user can saved file as "nobody" user.
On SLES 11 :
mount -v -o rw,soft,vers=3,nosuid,tcp,timeo=600,rsize=32768,wsize=32768,soft,intr 10.7.36.77:/vol/nfs2 /mnt/nfs2
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Thu May 24 13:55:15 2012

mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting 10.7.36.77:/vol/nfs2
Maybe there is a problem with SLES settings ???
