Prerequisites

This extension is in its alpha stage. As such your experience may not be completely free from consternation. You are expected to have a working knowledge of Shibboleth and Tomcat (or JBoss, whatever you use), and also:

  • An installed Shibboleth 2.x IdP
  • A SQL database of some sort (one that JDBC wrks with). This data base will be use to support the authentication method that allows a user to use a personal card to authenticate a managed card. Define a "personalcards" table with three text columns: id, ppid, pubkey.
  • A program to generate card images. These are 250x167 png images. You can stream a static png file or generate a custom image using, for example (netpbm required): 
    #!/bin/bash
# $1 = card_id : username
cardid="$1"
id="${cardid##*:}"
src=<some_dir>/card_background.ppm
mask=<some_dir>/$1.mask
pbmtext -font $font $id > $mask
pnmdepth 255 $mask | \
   ppmchange black linen | \
   pnmcomp -xoff=-20 -yoff=116 -alpha $mask -invert - $src | \
   pnmtopng
    If you can be content with the default card image, probably dependent on the Identity Selector, you can skip this step.
  • A JAAS configuration that will authenticate a userid and password. This is required regardless of whether or not you use tomcat for SSO authentication. Authentication of Infocards is backdoor and no browser is directly involved.
