commit 194fdee65f91e8ea88196d2cff1c678f868bb3df
Author: Jeremy Allison <jra at samba.org>
Date: Sun Feb 15 18:23:09 2009 -0800
Attempt to fix bug #6099. According to Microsoft
Windows 7 looks at the negotiate_flags
returned in this structure *even if the
call fails with access denied ! So in order
to allow Win7 to connect to a Samba NT style
PDC we set the flags before we know if it's
an error or not.
Jeremy.
