View client shows: Your Account is disabled while RDS Connection is active.

Hello,

we are running into a strange issue, users try to start another RDP Pool Application while a RDS Connection is already established, the view client shows the message "Your Account is disabled". We checked already everything and ended by the following discussion: View 6.2 bug?

griffjames talks about an extra security check which can be disabled, does anyone know how we can do this?

Thanks.
