[Samba] sharepoint services 3.0 and samba?

[Adam Williams]

I'm not really sure where to ask this, so please, no flames!  Has anyone 
been able to get microsoft sharepoint services 3.0 to work with 
authenticating my samba users that are in openldap?  I have SPS 3.0 
installed on a Windows 2003 Server that is joined to my samba domain and 
working ok, NT domain users can log into windows 2003 fine, but I can't 
get http://sharepoint to authenticate the users.  i've tried 
ADMIN\awilliam and just awilliam with my password, but it kicks me out 
with an "Access Denied" error after a few tries.  I'm not really sure if 
my problem lies with getting IIS to authenticate against samba/openldap, 
or if its a setting in sharepoint services, or what?  I've google'd but 
haven't came across anything helpful.  Any ideas?
