[cifs-protocol] nTDSDSA Object and serverreference attribute

[Sebastian Canevari]

Hi Matt,


Sorry, I thought I had sent you this before but it was saved in my drafts.

Today, I was wondering what may have happened to your response and found out I hadn't sent it after all.

My apologies.

=========================

What makes you think that the attribute was populated from a Windows 2008R2 server and not by Samba?

=======================

Thanks!

Sebas

Ok but then how to explain that windows 2008R2  actually populate this attribute.
Thanks for the information.
