From 4072006fecf56bebf113fe1d4566156c0d89bacc Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Wed, 9 Jul 2003 00:23:42 +0000 Subject: Get rid of DISP_USER_INFO/DISP_GROUP_INFO as they serve no useful purpose. Replace with an array of SAM_ACCOUNT/DOMAIN_GRP entries. ZERO struct's in smbd/uid.c stops core dumps when sid_to_XX functions fail. Getting ready to add caching. Jeremy.
