I recently did a clean install of my Drupal server, including the MySQL database.
Shibboleth authentication is working fine, but attempting to set up a group rule gives the following:

warning: array_keys() [function.array-keys]: The first argument should be an array in /home/inqueri/WWW/sites/all/modules/shib_auth/shib_auth.module on line 495.
warning: Invalid argument supplied for foreach() in /home/inqueri/WWW/includes/form.inc on line 1192.

line 495 is:
'#default_value' => array_keys($options[3]),

I have checked the backup I made before I reinstalled, but can't find any clues there - and I had a group rule working just fine in the previous install. Can anyone offer me a suggestion?

TIA,
