Secure Global Desktop resume each other’s Windows sessions

Hi,

we have sgd 4.7 with RDS in Windows 2008 and the following configuration :

in SGD 2 users : juan and pedro
in windows 2008 1 user : nomina

the two users (juan an pedro in SGD) share the same user ( nomina ) to connect to the server 2008 with RDS

scenario:

1. Juan logon in SGD and launches the application
2. pedro logon in SGD and launches the application, in this moment, SGD resume the session of juan.

guess it's because they share the same user ( nomina ) in windows 2008

What should I change to SGD handle session resumability and not RDS ...?

thanks
