Subject: dfs referral for sysvol and windows XP

Hello doc help,

While revisiting the DFS implementation for samba I remade some tests with XP and It seems that when doing the last step in order to resolve \\domain.tld\sysvol.
Even if we tend to send the same frame, XP comes to samba 4 when asking for a DC holding \\domain.tld\sysvol. So as we support this level we return entry for this level.

But then it fails to connect to \\dc.domain.tld\sysvol and keep doing ntlm connection to \\domain.tld\sysvol.

Is this "normal" ?

I put another capture here: http://www.matws.net/mat/misc/dfs2.pcap.gz
where we can clearly see that the client starts to do NTLM auth to connect to \\domain.tld.

Thanks for your answers.
