From a70f5d36ac0d28f9eb4ea3e92483684c8da67a67 Mon Sep 17 00:00:00 2001 From: Jeremy Allison Date: Mon, 6 Jan 2014 15:22:59 -0800 Subject: [PATCH] s3: winbindd: Move calling setup_domain_child() into add_trusted_domain(). Ensure it only gets called when a new domain is allocated and added to the list. This should fix problems with the previous logic where setup_domain_child() was called in places where an existing domain was returned.
