NFSv4 with sec=krb5 mounts not working under Solaris

[Erich Weiler]

Hi All,

I've been beating my head against this for a while now and thought I'd 
post here to see if anyone knows where I'm going wrong.  I installed 
MIT's Kerberos on my Solaris 10 box, using krb5 to authenticate against 
a Kerberos server running Fedora Core 5.  Works great, I can SSH in to 
my Solaris 10 client and get a ticket and things are groovy.

What I'd like to do now is mount an NFSv4 mount from that same Fedora 
Core 5 box with sec=krb5 as a mount option.  What I did:

1: On the Solaris 10 client, I ran kadmin:

kadmin: addprinc -randkey nfs/solaris10host.domain.com
kadmin: ktadd -e des-cbc-crc:normal nfs/solaris10host.domain.com

/etc/krb5.keytab file was created successfully.  Then, as root on 
solaris10host:

% mount -F nfs -o vers=4 -o sec=krb5 nfs4server:/ /mnt
nfs mount: mount: /mnt: Permission denied

Can't figure out where I'm going wrong.  Does anyone have any ideas?

Thanks a million in advance,
erich
