From 5ebbd46b4a8714e98bb14862f9c3dc31301d8404 Mon Sep 17 00:00:00 2001 From: Matthieu Patou Date: Fri, 24 Feb 2012 16:13:10 -0800 Subject: s3-winbindd: Close netlogon connection if the status returned by the NetrSamLogonEx call is timeout in the pam_auth_crap path If not the child process would hang for quite a long time up to the moment when the connection is cleaned by the kernel (took ~ 20 minutes) in my tests.
