https://www.flexnetmanager.com/Suite/ you are immediately redirected to the page to select a tenant. Even if a tenant that the user
is configured in a role for is selected at this point, you are still taken back to the ?403: Unauthorized? page.

This is because we user cookie to remember previous tenant login information. when the Tenant Role is disabled, User login will be lead to URL https://www.flexnetmanager.com/Suite/Login/Failure/NoAccess
