PHP and PAM

Hello I tried to used PHP with autentification.... I wrote script, but I had got error : Fatal error: Call to undefined function: pam_auth() in /usr/home/httpd/html/farm/dev/test/user.php on line 2 I read some FAQ and I found the answer: .... For some reason, newer version of php4 do not always seem to properly update the autoconf stuff when your run the buildconf script. If you get this error, configure php again and then look through the autoconf output and look for a line that says "Checking for Pam Auth support: yes". If you don't see it, it isn't getting built in. To fix this, run the command 'autoconf' in the top level php source directory, this should update the configure script to recognize the pam auth stuff. .... I was trying to configure PHP with "Pam Auth support", but I can't find this opitions. I looked all option from ./configure and there is nothing... Server use FreeBSD 4.1.1 -- R.
