[Samba] latest Samba 4 does not look in keytab

[steve]

Hi
After upgrading to
Version 4.0.0alpha18-GIT-24ed8c5 on Ubuntu 11.10, Samba 4 no longer 
looks in the keytab for my nfs server entry:

mount -t nfs4 foo bar --o sec=krb5
Kerberos: AS-REQ nfs/hh3.hh3.site at HH3.SITE from ipv4:192.168.1.3:53213 
for krbtgt/HH3.SITE at HH3.SITE
Kerberos: UNKNOWN -- nfs/hh3.hh3.site at HH3.SITE: no such entry found in hdb

The nfs entry is in the keytab:
klist -ke /etc/krb5.keytab
Keytab name: WRFILE:/etc/krb5.keytab
KVNO Principal
---- 
--------------------------------------------------------------------------
    1 nfs/hh3.hh3.site at HH3.SITE (des-cbc-crc)
    1 nfs/hh3.hh3.site at HH3.SITE (des-cbc-md5)
    1 nfs/hh3.hh3.site at HH3.SITE (arcfour-hmac)

How do I tell this new version to look in the keytab? or,
How do I add the nfs internally?
Thanks,
Steve
