Resolution: Cannot Reproduce
Affects Version/s: 1.5
Fix Version/s: None
I created a user role that did not have permission to manage civicrm groups.
I then disabled a civicrm group.
I logged in as the user without group management permission.
I was able to either 'disable' or 'enable' that newly disabled group. This did nothing in reality - either choice led to the management options being removed.
Not sure if this is a drupal issue or a civicrm issue.
