Logging in to Portal Studio and Portal Interface on the same browser

[CR #339693] If you are already logged in to Portal Studio and use the same session of the browser (by pressing Ctrl+N) to access Portal Interface, the information entered in the login window is not used. Instead, the Portal Interface uses the access permissions belonging to the user ID logged in to Portal Studio.

Workaround: Do not use the same browser session to log in to both Portal Studio and Portal Interface.
