From: Volker Lendecke <vlendec@samba.org>
Date: Mon, 10 Oct 2005 19:57:55 +0000
Subject: r10878: Reply to some comments by tridge and metze:

* rename the composite helper functions from comp_* to composite_*

* Move the lsa initialization to wb_connect_lsa.c

* Equip smb_composite_connect with a fallback_to_anonymous

The latter two simplify wb_init_domain.c quite a bit.
