This much we already have, on a 'workstation self exclusion' level, it's
the 'allowed workstation' (sambaUserWorkstations in LDAP I think)
attribute in the passdb.
Now, the main failure it is that's set by netbios name, so fails as soon
as the user tries to use smbclient, and sets that for themselves. We
could honour the ldap records that pam_ldap uses, that add a DNS/IP host
restriction. (However, this faces problems with member servers, as they
do not pass us on that information).
