Central NIS & NFS

[Guilherme J. R. Oliveira]

Hi.

I will configure a webhosting network that will serve PHP and ASP pages.
PHP pages will be served from a freebsd server and that's it !
For the ASP server, I want that w2k authenticate to freebsd and then the 
ASP webpage will be retrivied in freebsd to IIS.
So I want a central server for logins and files in FreeBSD that w2k can 
acess.

I've searched google and I think the best way to do this is using NIS+NFS.
W2k authenticates using NIS and if it's requested an ASP web page it 
will be served by IIS using the ASP files in nfs/FreeBSD.
So it comes another problem: nis+nfs clients to w2k ...

It seems that Microsoft as a product called "Services for Unix" in 
http://www.microsoft.com/windows/sfu/default.asp that have these clients.
Anyone tried this ? It's stable ?

Other possibility (if i understand right) is to use Samba as Active 
Directory to authenticate logins and serve the files by shares.
Is this possible and stable in Samba ?

Other possibility is CHilisoft ASP but it's not current as it only 
support ASP 3.0 and I will need .NET too.
Ao this option is discarded.


Opinions ?

Thanks !
