posix_getpwnam() and other functions

[Anon]

Hey,

I'm trying to use some of the posix functions in order to do some user authentication through PHP. I've done it successfully with Perl's use of Pwent, giving me access to getpwnam(), getpwuid(), etc. I saw that PHP supported these functions through POSIX, so I recompiled my PHP server to allow the use of those functions, and had no luck using them. Every single time I attempt to do any form of user authentication against the machine, it just returns null fields. any use of other posix functions to get machine information works, but not any of the ones regarding user information. Has anybody worked with this POSIX stuff before or know why it isn't working?

Thanks ahead of time.
