"Authentication box" on BI Launch Pad (BOBJ 4.0)

Hi All,

How do I enable the "authentication box" to choose the authentication type on BI launchpad (BOBJ 4.0)?

All others applications shows the "authentication box" (WebI Rich Client, for exemple).
The CMC web page shows this "authentication box" too.
Only in BI Launchpad don't show this box.

Thanks and Best Regards,
