Do you have members that you want to be able to log in and see member only content and update their details, but only while they are active members?
Have various levels of admins and users who need access to different levels of configuration?
Have regional admins who should only have access to contacts in their region?
This is all possible thanks to Drupal user roles, CiviCRM relationships, our CiviCRM related permissions extension and the CiviCRM roles sync modules. We can accommodate all levels of access complexity.
