I have a requirement to enable logging into a new Drupal powered site using the military Common Access Card/Personal Identify Verification system.
I have come across this module: http://drupal.org/sandbox/larquin/1292622 but there is no code.
Is there a module for Drupal available? If not, does anyone know of any PHP (or for that matter any other language) sample code I can take a look at to base a module on?
Or, is there another approach to supporting this authentication approach that does not require a dedicated module? (e.g. ActiveDirectory? Apache configuration? etc)
