From c2729d59a631822c7e5545d13a2eff8ed237401b Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Mon, 18 Feb 2002 11:07:57 +0000 Subject: serialise all domain auth requests this is needed because W2K will send a TCP reset to any open connections that have not done a negprot when a second connection is made. This meant that under heavy netlogon load a Samba domain member would fail authentications.
