Ouch, very NFS (well, non-kerberos NFS at least).. :-)

So, in other words, changing the pbs_server to ignore this
info from the client and just use its own info sources to get
the hostname will fix this in a backwards compatible way ?
i.e. look up clients IP address to get its purported hostname
and then check that the purported hostname resolves back to
the clients IP address..
