When a Client Access print session is not configured correctly and is launched, the user name is already there and cannot be changed. This is caused by having the wrong connection options selected when configuring the session. To correct this, go into Start -> Programs -> IBM AS/400 Client Access -> Operations Navigator, right click the wescprod.cubase.org connection and choose properties. In the properties window, select connection and change the option for login to "Prompt Every Time" After the session is restarted, the user will be required to enter a user name as well as password.
