commit 945bbd14bb1c8ec11365d52a7897ca17e95c9053
Author: Gerald W. Carter <[EMAIL PROTECTED]>
Date:   Mon Jan 28 11:32:09 2008 -0600

    Restrict the enctypes in the generated krb5.conf files to Win2003 types.
    
    This fixes the failure observed on FC8 when joining a Windows 2008 RC1
    domain.  We currently do not handle user session keys correctly
    when the KDC uses AES in the ticket replies.

commit 2ced9b906fe9044edf6efbca6175aa481c2a4451

    r24771: Use infolevel 25 to set the machine account's password (just like 
winxp).
    This correctly updates pwdLastSet field on win2k3 server.
