User privileges

Hi there,

In JIRA I have created a new user group ('jira-basic') that only allows those users to effectively browse all of the issue and content. They do not have the ability to modify or delete content.

In GreenHopper I have enabled the "Need Scheduling Permission" setting. This works to some degree in that the 'jira-basic' users are not able to drag issues into the schedule boxes, under the "Planning Board" view. However, these users are still able to drag issues from column to column (i.e. to-do -> in progress -> verify -> done etc).

How can I prevent these users from dragging issues into different columns?

Thanks in advance for any help
