commit e7e1e1887e79e4dcbd8836b775e387751c44f318
Author: Günther Deschner <gd at samba.org>
Date:   Tue Sep 8 11:57:52 2009 +0200

    s3-schannel: Fix Bug #6697. Interdomain trusts with Windows 2008 R2 DCs.
    
    The Schannel verifier (aka NL_AUTH_SIGNATURE) structure (32 byte) sent from a
    W2k8r2 DC is passed in a buffer with the size of a NL_AUTH_SHA2_SIGNATURE (56
    byte). We should just ignore the remaining 12 zeroed bytes and proceed.
