[CentOS] kerboros and nfs v4

My mamnager's trying to get nfs v4 working with kerboros. One major issue
is that we do *not* have access to the server, or ktadmin - that's the
network folks, and they have AD on the other side. The result is that he
can't create (if I have this right) objects.

I found
<http://sadiquepp.blogspot.com/2009/02/how-to-configure-nfsv4-with-kerberos-in.html>,
and he says he's done everything and more.

Any pointers, suggestions, etc?
