Hide "Assignments & Permissions" panel under Administration

Hi,

I want to hide the tab "Administration" when the end-users login into the user application. The users can only request workflows and approve them under the work dashboard tab. Therefore, I was able to hide the tabs like "Roles and Resources" using the Navigation Permission settings under the RBPM Provisioning and Security.

However, I am unable to hide the "Administration" tab. I was able to hide some of the links under the Administration tab. I am to see the "Administrator Assignments" and "Team Configuration" links still present in Administration tab.

Please let me know if there is a way to hide the whole of "Administration" tab.

Thanks,
Maverick
