[Samba] authenticating IIS 6.0 against samba?

Fri Sep 11 12:00:15 MDT 2009

I have a windows 2003 server joined to my domain.  I'd like to have IIS 
6.0 on the 2k3 server authenticating against samba so that windows 
sharepoint services can be used.  I've tried getting NTLM authentication 
working following instructions at 
http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/7258232a-5e16-4a83-b76e-11e07c3f2615.mspx?mfr=true 
but I'm not having hany luck.  I'm still getting access denied errors 
when trying to authenticate users in sharepoint services.  Has any one 
got this working, and if so, any tips?
