Raw Blame History

Copyright (c) 1996-2001 Microsoft Corporation
Module Name:
winrnr.c
Abstract:
Rnr provider for ActiveDirectory.
Work items:
1) Need to support the NTDS Global catalog on LUP_DEEP from Root searches.
2) Need to add bind handle caching.
Author:
GlennC 23-Jul-1996
Revision History:
GlennC Added support for LUP_CONTAINERS in NSP2LookupServiceXXX
functions.
jamesg Jan 2001 cleanup, bug fixes, proper alignment
jamesg May 2001 rewrite
- 64-bit completely broken because 32-bit
structures used as bervals
- leaks
- duplicate code
- simplify flat buffer building macros
- allow for sockaddrs other than IP4
