From 5b5eb35c91ec400a25f6e6cf3eec421bd9560d50 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Sat, 13 Jun 1998 03:04:00 +0000 Subject: Makefile: Added ubi_sLinkList.o as the groupname.o file needs it. Added groupname.o includes.h: Added ubi_sLinkList.h include. loadparm.c: Added groupname map parameter. password.c: Fix HPUX big_crypt. username.c: New user_in_list() code. Moved groupname map code to groupname.c lib/rpc/server/srv_util.c: Added lookup_wellknown_sid_from_name(). New groupname map stuff. Note that nothing currently uses this but at compiles ok. Jeremy.
