When I am using the web administration, and hit the sessions tab, no sessions will be shown even though there are multiple connections made. It will show an error saying that it's "Unable to retrieve sessions. An internal error occurred."
When looking in the webadmin log the following exception is thrown with the error code:
SEVERE: com.sun.ut.service.ServiceException: ut_setUserSessionEnt,
ErrorCode: -5 (UT_NOPERM - no permission)
