From 768515f4ad13785729fcd4df7cecaede39b7409a Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Wed, 23 Jul 2008 16:19:54 +1000 Subject: The SMB session key must not be more than 16 bytes in SAMR (and presumably LSA). Tests show that Vista requires the sesion key to be truncated for a domain join.
