commit 5188f2861137ff06d5399561d55d7d00c3a08644
Author: Jeremy Allison <jra at samba.org>
Date: Thu Jun 26 14:02:39 2008 -0700
From Steve Danneman @ Isilon.
Attached is the companion patch to
(037b9689d9042a398cb91e4628a82fcdfa913c21), which
made handling of WINBINDD_LIST_GROUPS asynchronous.
Because most all of the list_groups code was reusable, I abstracted it,
and implemented both list_groups and list_users on top of it.
On my large test domain a "wbinfo -u" call went from 70 seconds to 30
seconds with this patch. Plus, the parent process is no longer blocked
from receiving new requests during that time.
