>Description:
If you umount a nfs-mountpoint, the server will not get an
authentificated umount request. If you unmount it with the full
path it works. With Linux 2.2 and Irix 6.5.2 as clients both
'umount /mountpoint' and 'umount somehost:/somedir' work.
>How-To-Repeat:
Client:

# mount somehost:/somedir /mountpoint
# umount /mountpoint

Server:

# showmount 
>Fix:
workaround (no fix !):

# umount somehost:/somedir
