Start a TMUI session on SSL Orchestrator and log in if prompted (Components > SSL Orchestrator > ACCESS > TMUI)
From the Main menu on the left, select Access > Overview > Active Sessions. The following screen should appear. You should see an Active Session Count of 0 and that there are no sessions listed in the table.

Open the RDP file to connect.
At the authentication prompt, click on More choices to show additional logon options. Then click on Use a different account.
