If you go into the account manager and edit that user, expand the IP SLA section at the bottom, and select 'None' for all the options, the entire module link will disappear from the list at the top of the page while that user is logged in. It works the same way for the other modules.
Hi TPatterson -
This would be an enhancement request...
The wireless module had that problem, but I wouldn't have expected any of the newer ones to behave that way. Are you sure you're logging in with the modified user?
