[Samba] "DNS update failed" during ads join

[Joshua Swink]

I received the warning "DNS updated failed!" during net join. Is this
an important warning? Will there be problems?

Immediately after the join, clients using smbclient were able to
authenticate and access shares on this server - even though "net ads
testjoin" complained about kerberos problems.

# net join -U Administrator
Administrator's password:
Using short domain name -- ENGWIN
DNS update failed!
Joined 'ENGFILES00' to realm 'ENGWIN.UCMERCED.EDU'

Thanks in advance
