PAMPOP

This pam module does authentication by logging into a pop server. It's an ugly hack but it works.

Usage

In the pam configuration for the service you want to auth against pop, include a line like: 

auth     required       pam_pop.so my.popserver.com

Don't include any other arguments except the pop server.
