Description:
------------
I have installed pam_auth for use within a php script. In PAM i use pam_krb5.so. It works fine with local accounts. Because i do not want local accounts i tried to config pam with /lib/security/pam_permit.so for account and this doesn't work.






Reproduce code:
---------------
pam config

==========
auth    required          /lib/security/pam_krb5.so  debug
account required         /lib/security/pam_permit.so
===========

Expected result:
----------------
$error = User not known to the underlying authentication module (in pam_authenticate)

This is most likely a problem with you pam setup and not the pecl/pam extension. This is the config file I use with PHP and pam_krb5.so, please try adding "no_user_check" and the "session" line.

[mikl@example ~]$ cat /etc/pam.d/php
#%PAM-1.0
auth            sufficient      /lib/security/pam_krb5.so realm=EXAMPLE.COM no_user_check
account         required        /lib/security/pam_permit.so
session         required        /lib/security/pam_permit.so

Btw, that should be:

auth   required   /lib/security/pam_krb5.so realm=EXAMPLE.COM no_user_check

(This particular site has multiple realms with corresponding "auth" statements, the last one must have "required" set however)
