I attached dump from wireshark. If raw tcpdump would be more helpfull I can do
that as well.

Is seems that is has no problem with GSS_S_NO_CONTEXT as one can see. It looks
like the server returns NFS4ERR_PERM.

this is how my exports file looks like:
/mnt/export/nfs4   gss/krb(rw,sync,fsid=0,no_subtree_check)

ls -ld /mnt/export/nfs4/
drwxr-xr-x 2 root root 6 2008-03-07 16:11 /mnt/export/nfs4/
