CiviCRM Community Forums (archive)

We're new to Drupal and CiviCRM and just had our site moved to a new server.  We are trying to manage our users through the Drupal side so that we only have to add and delete users once using Drupal and then would like the CiviCRM side to reflect those same changes. We use CiviCRM to display contact info of our users.  Adding people is fine; they all show up in the CiviCRM profiles.   But deleting users from Drupal does not delete them from CiviCRM.  Running synchronize users to contacts does not make the users deleted in Drupal disappear from the CiviCRM.  Any ideas on what the issue might be and how to fix this would be greatly appreciated.

Thanks.  Can you explain further what it means to implement a hook_user?  This is the description I found of it: http://api.drupal.org/api/function/hook_user/6 and I don't understand it.
