I'm running a recent git checkout (about 2 day old), waf build,
installed (using waf install).

Setup was a standard provision - nothing special.
The samba4 version has been updated several times and the
data was migrated using upgradeprovision.

DNS Server is bind 9.6.1P3 (with samba patches) running on the
same machine.

Several test clients are joined to the domain win2k8, win7, win-xp
and Samba 3.x.

What else do you need to know?

CN=S4-DC1,OU=Domain Controllers reports:
   ms-ds-KeyVersionNumber: 18

Same KVNO as listed by "klist -ke secrets.keytab".

Any idea where else we could look for the older KVNO?
I've done a quick ldbsearch on all .ldb files - without any luck.
