Subject: [PATCH] Drop full domain when constructing the Ad hostname.
When trying to use the special MS Windows hostanme we need to stop
at the first '.' if we got a FQDN from gethostname()
Tee HOST$@REALM form in fact uses the AD samAccountName attribute to
represent 'HOST', and that attribute is always the host's shortname.
Characters like '.' are actually illegal for a shortname in AD.
