If you’re running a site using Joomla you’re no doubt aware that some things which appear to be straight forward with a Drupal base aren’t so easy. Both Joomla and Drupal have their strengths and weaknesses, I just happen to be a long way down the Joomla path.
A big issue for me was how do I restrict access to my site depending on memberships to a real world (non internet) organisation. All my members have an entry in the CiviCRM database but many will not have a CMS login. Out of the box there was no real way of achieving this without getting into LDAP territory.
