the remote sever, and to query it for domain information.
Provide and use this information in the SamSync/Vampire callbacks, to allow a
parallel connection to LDAP, if we are talking to AD. This allows us
to get at some important attributes not exposed in the old protocol.
With this, we are able to do a all-GUI vampire of a AD domain from
SWAT, including getting all the SIDs, servicePrincipalNames and the
like correct.
