commit c780a666920a5efc06b29335d4ae78f1eca6b66a
Author: Jeremy Allison <jra at samba.org>
Date: Tue Oct 14 16:08:14 2008 -0700
Attempt to fix bug #5818 - "smbcacls: sorts ACEs improperly and loses inheritance", based on
a patch from Paul Fertser <fercerpav at gmail.com>. I also added the ability to get/set hex
and symbolic inheritance flag names on ACE flags. I'm still investigating the effects
of setting the "SEC_DESC_DACL_AUTO_INHERIT_REQ" flag as I don't yet see what effects
this is having on the ACE sent.
Jeremy.
