r685: The SAM is dead! Long live the new SAM! ;-)

This commit kills passdb, which was only hosting the auth subsystem.

With the work tridge has done on Samba4's SAM backend, this can (and
now is) all hosted on ldb.  The auth_sam.c file now references this
backend.

You will need to assign your users passwords in ldb - adding a new line:

unicodePwd: myPass

to a record, using ldbedit, should be sufficient.  Naturally, this
assumes you have had your personal SAMR provisioning tutorial from
tridge.  Everybody else can still use the anonymous logins.
