commit 8e0fa453a3d0a2c997a935b6940796612c972708
Author: Volker Lendecke <vl at samba.org>
Date: Tue Mar 11 14:15:52 2008 +0100
Convert mapping_tdb.c to dbwrap
I know, this is not used anymore, but until ldb knows about ctdb which is
blocked by the lack of transactions in ctdb, a tiny patch reactivating
mapping_tdb.c might be needed for cluster setups.
commit 38bb69cb316ba605a6d3a4454b986cb63ace3c21
Author: Volker Lendecke <vl at samba.org>
Date: Tue Mar 11 12:53:50 2008 +0100
Clean up add_mapping_entry slightly

Author: Volker Lendecke <vl at samba.org>
