user authentication with IIS ??? (newbie)

[Anon]

Hi,

I need any kind of user authentication...

I'm using php4.0.0 on a NT4.0 Server with IIS4 and Oracle 7.3.3 DB. My problem is, that only a few people should be able to change things on the database.
First, I tried to do a user authentication with NT, but that was a real mess. PHP complaint about not finding include files and posted some error messages.
After that, I checked out the "HTTP authentication with PHP" Chapter in the manual. Ok - won't work with IIS....

Has anybody of you an idea of how to create a simple user authentication??

Thanks in advance...
