NT Authentication through UNIX via PHP

[warewolf55]

I am re-building an intranet page for my company in PHP. My Apache server resides on a UNIX box and my "security" is set up so that if you want to get to the website you must log in using a UNIX username/pass. This requires all new users to have a UNIX id setup. What I want to do is have the users log in with their NT username/pass and have it pass through the UNIX box to an NT PDC/BDC (we are not ready to use AD yet), based upon the NT user group the user belongs to they will be allowed/denied and redirected to a different page.

I am learning PHP as I go, so the going is pretty slow, age works wonders on the memory. I have googled every combination I can think of and thus far I have found only LDAP solutions or solutions that require MySQL or SQL. I know this has to be possible and I know that someone, somewhere has done it.

So my question to this illustrious group of technically minded folks is, HOW? How do you authenticate through a PHP page to a UNIX box to an NT Domain Controller?

LDAP and Active Directory is the way to go, unless maybe your Unix box uses PAM? I came across
