1) Make sure you have these libraries:
pam_krb5.i386
pam-devel
pam
pam_ccreds
krb5-devel
sudo yum install
(Assuming you already have Kerberos / Pam installed and configured to your liking)
* You need Pecl/Pear to get this part to work
2) pecl install pam
3) If this fails (an error about not enough memory) Increment the memory given to Pear by editing: "/usr/PEAR/pearcmd.php"
with something like " @ini_set('memory_limit','12M'); "
4) Open up /etc/php.ini add: "extension=pam.so" in the dynamic library section (or wherever you want)
5) Create a file called: /etc/pam.d/php and put in a configuration like this:
auth sufficient pam_krb5.so debug
auth required pam_deny.so
account [default=bad success=ok user_unknown=ignore] pam_krb5.so debug
6) Restart httpd
7) Enable PAM in Moodle: "Users" >> "Authentication"
You can test 'pam' in general by doing:
<?php
if (function_exists('pam_auth')) {
if(pam_auth('jel65','xxxxxxx')) {
echo "SUCCESS!";
}
else {
echo "FAIL!";
}
}
?>
and also try: <?php echo phpinfo(); ?> (it should have PAM module installed
To really see if it's authenticating go to:
"less /var/log/secure"
I hope this helps somebody!
