Quite some time ago I posted an entry here about configuring Apache to authenticate against an NT4 Windows domain using PAM. That was on an older Fedora box. The original post is here:

On a new Debian box, a very simular configuration failed. The Apache server recorded this message in its error log:

Internal error: pcfg_openfile() called with NULL filename

It turns out that later versions of Apache expect a users file even if the authentication method does not use one. The fix is to add an additional directive to protected block in Apache's configuration file.
