Service Portal Profile Message re Requested User Not Found

[balston]

Non-itil user cannot access a particular category on the end-user portal.  The non-itil user gets the message, "Logout Successful" when trying to access the end-user portal.  Also, when the admin impersonates the user, the admin can get to the portal and the widgets as the impersonated non-itil user.  But, when the admin also clicks on "Profile" to the see the impersonated user's profile, the message comes up, 'Requested User Not Found'.  The user has the snc_internal role.  The Admin has also impersonated other users and did not get this message.  And no other user has reported not being able to access the end-user portal.
