For transparent authentication the client workstation must be a member of
the domain that the jcifs.http.domainController machine is an authority
for or has a trust relationship with the DC that is an authority for the
target domain. However, if there is no such relationship (e.g. someone
just plugs in their laptop without joining any domain) I should still work
but the password dialog will pop up into which the user must enter valid
credentials for the domain that the jcifs.http.doma ... (repeat of above).
