The one thing that the 'vampire' process will not do is return the
plaintext password.  This means that Samba cannot set the 'ldap
password'.  Your options are to use pam_winbind on your local machine,
and authenticate local users against Samba, which then works against the
NT and LM passwords we do have, or to use the Heimdal Krb5 snapshot
described in 
and pam_krb5.

Or you can try and have pam_ldap -> OpenLDAP -> SASL PLAIN -> PAM ->
pam_winbindd -> winbindd -> OpenLDAP...

Yes, I know this sucks, and I've tried to have discussions with the
OpenLDAP folks about how we could have OpenLDAP authenticate against
these passwords in a sensible way, and the infrastructure was simply not
up to it.
