samba - Dec 2013 - Failed to parse NTLMSSP packet; Potential return of bug 7577?

Hello,

I try to track down an issue with Windows 8 authenticating to Samba 3.6.22.
Today I faced a strange issue that I could not connect to my server using 
hostname but I could perfectly do so using IP-address.

- \\skynet\share did not work ("The parameter is invalid")
- \\10.0.1.6\share did work

After lots of searching and trying I was mainly concerned about the following 
error logged over and over again:

[2013/12/16 02:23:13.573666,  1] libsmb/ntlmssp.c:255(ntlmssp_update)
   Failed to parse NTLMSSP packet, could not extract NTLMSSP command

After increasing log level I found this logged:

[2013/12/16 02:23:13.573666,  1] libsmb/ntlmssp.c:255(ntlmssp_update)
   Failed to parse NTLMSSP packet, could not extract NTLMSSP command

Looking for similar issues with NEGOEXTS dumps I found bug 7577 
(<https://bugzilla.samba.org/show_bug.cgi?id=7577>). Which was supposed to
be
fixed since version 3.5.4 and therefore should be fixed in my 3.6.22 too.

I have also scanned the discussion about Live Sign-In issues on the list: 
<https://lists.samba.org/archive/samba-technical/2010-July/072321.html>


After having read this I have disconnected my Microsoft Account from my Windows 
profile and suddenly my shares now work as expected. Though I cannot use the 
Windows Store any more on Windows 8 then.


Can anybody confirm that this (or similar parsing issue) returned in Windows 
8(.1) now?

I am running Samba 3.6.22 as a domain controller for Windows 8.1 Professional 
64-bit as a trial right now. Also roaming profiles occasionally report "The
parameter is invalid" on profile synchronization which might be related to
the
same issue as I was used to connect my user profiles to a Microsoft account.


Shall I file a bug for this?
