Connecting to Samba from Vista RC1

Posted on September 21, 2006 by Brian Jepson

One of the things that is annoying me about Vista is that I can’t
connect to my SMB shares on my Mac. When I try to log in, it rejects my
password. I looked at /var/log/samba/log.smbd on my Mac, and here’s
what I saw:

[2006/09/21 13:55:45, 1] auth_ods.c:opendirectory_ntlmv2_auth_user(312)
  User "bjepson" failed to authenticate with
"dsAuthMethodStandard:dsAuthNodeNTLMv2" (-14090)  :(

So I poked around the Group Policy Edit (type gpedit.msc into the
search or address box and press enter). I drilled down into:

Local Computer Policy
  -> Computer Configuration
    -> Windows Settings
      -> Security Settings
        -> Local Policies
          -> Security Options

and I changed “Network security: LAN Manager authentication level” to
“Send LM & NTLM – use NTLMv2 session security if negotiated” and it
seems to work.

    Thanks, Chris. I didn’t know that Microsoft distributed client bits for Services for Mac. What I’m trying to do is connect from Windows to a Mac Samba server, though. Since this is a client authentication module for the Mac, I’m not sure how it would integrate with the Samba server on the Mac.

    Thank you very much, sir. I’ve been itching to hack around on Vista, but I’m a Mac guy too, so ran into this problem within moments of getting a Vista machine built. Problem solved.

    Thanks again.

    “Brilliant!” i thought to myself as I came across this page.
    “Blast!” i thought to myself as I reaslised my crappy work computer has Vista Home installed and apparently no gpedit.msc.

    Any ideas on how to achieve a similar result on Vista Home?

    Paul,

    Start up regedit and change this value:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LMCompatibilityLevel from a 3 to a 1

    Thanks Yvo!

    Worked perfectly once I’d made the change as you described.
