Drupal is required as a base system for [[CiviCRM]]. In addition, to fully support the GENVASC workflows, two functions are performed by custom-built Drupal modules. [[genvasc_labels]] generates a random GENVASC ID, stores it to prevent re-use and prints ID labels for use on GENVASC recruitment paperwork. [[ice_messaging]] is a visualisation wrapper for the database created to receive HL7 messaging from the Sunquest ICE system to alert the LCBRU about the arrival of GENVASC specimen at the pathology department. Currently uhlbriccsapp04.xuhl-tr.nhs.uk is a drupal/CiviCRM test installation and uhlbriccsapp05.xuhl-tr.nhs.uk is a drupal/CiviCRM live installation. Drupal version 7.15 deployed on 17 Sept 2012 [[Notes on Drupal and LDAP configuration ]] - used to create user accounts, and associate the user accounts to the 'LCBRU staff' group. Enable the Apache 'rewrite' module to allow clean URLs to work.
