Subject: [PATCH] join/update: set dNSHostName if not set
If during a join or update an existing AD computer object does not have
the dNSHostName attribute set it will be set with the current hostname.
This is important for cases where the user doing the join or update only
has "Validated write to service principal name" for the computer object.
The validated write with fully-qualified names can only be successful if
dNSHostName is set, see [MS-ADTS] section 3.1.1.5.3.1.1.4 "Validated
Writes - servicePrincipalName" for details.
