From 6ad78f01a5982666c83025a94ce4ff3729d5db6f Mon Sep 17 00:00:00 2001
From: Andrew Bartlett <abartlet@samba.org>

Subject: Rename hdb_ldb to hdb_samba4 and load as a plugin into the kdc.

This avoids one more custom patch to the Heimdal code, and provides a
more standard way to produce hdb plugins in future.

I've renamed from hdb_ldb to hdb_samba4 as it really is not generic
ldb.
