From edcd03b9c5f3b3c126c7ba5cfcb070573343fca7 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Wed, 17 Feb 2010 10:46:21 -0800 Subject: [PATCH] Fix bug #6557 - Do not work VFS full_audit Re-arrange the operations order so SMB_VFS_CONNECT is done first as root (to allow modules to correctly initialize themselves). Reviewed modules to check if they needed CONNECT invoked as a user (which we previously did) and it turns out any of them that cared needed root permissions anyway.
