The MRBS (Meeting Room Booking System) block integrates the
MRBS project by using settings in the Moodle config.php to authenticate against the mdl_user file as its external database and thus allows for single sign on. While initially designed to work with Moodle 1.6 as a single sign on integration, later work made the MRBS project a contributed Moodle block. Stephen Bourget was kind enough to work on some changes to prepare the MRBS block to take advantage of roles and for use with Moodle 1.7 and beyond. As a result of these integrations, the MRBS integration/block is no longer supported or maintained for versions prior to Moodle 1.7.
