From 78754ab2c9b28ea8ab09d3fd1f5450abe721a2c1 Mon Sep 17 00:00:00 2001 From: Günther Deschner Date: Wed, 6 May 2009 19:29:01 +0200 Subject: s3-netlogon: Fix NETLOGON credential chain. Fixes Bug #6099 (Windows 7 joining Samba3) and probably many, many more. Jeremy, with 9a5d5cc1db0ee60486f932e34cd7961b90c70a56 you alter the in negotiate flags (which are a pointer to the out negotiate flags assigned in the generated netlogon server code). So, while you wanted to just set the *out* negflags, you did in fact reset the *in* negflags, effectively eliminating the NETLOGON_NEG_STRONG_KEYS bit (formerly known as NETLOGON_NEG_128BIT) which then caused creds_server_init() to generate 64bit creds instead of 128bit, causing the whole chain to break. *Please* check.
