PHP web authentication using system accounts


what i would like to know is how to use php for authenticating system users through web. ie, the user will enter the username/password in a web form and the php in the server should use the server system user account and password to authenticate the user.

First I tried to run
su command to do the trick. but the command says that the standard in must be a tty, but php doesn't support pseudo terminals by default.

Then i pathched the php source with PTY support froMichael Spectorm of It seem not to work properly. Does anyone have a better idea or have done this properly? My code doesn't seem to work the same always...

kindly help...
