It should be noted that one of the reasons why it generally isn't 
recommended to use something like mod_auth_pam authentication, even with 
SSL, is that unlike sshd and other shell login mechanisms, there is no 
limit on the speed or quantity of login attempts (unless they've fixed 
this in recent years), which can leave your machine vulnerable to brute 
force attacks, or even with strong passwords, the denial-of-service side 
effects of such attacks.

If access to the web server isn't inherently limited to a LAN, you 
should consider limiting access (via Apache or a software or hardware 
firewall) to a specific network or set of IPs.
