SAP Authentication BI Launch Pad

Hi,

I need the authentication pulldown to be displayed in BI Launch Pad. I have gone through the steps in the guide i.e.

1. Create a new file called "BILaunchpad.properties" in the following directory

D:\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\warfiles\webapps\BOE\WEB-INF\config\custom

2. Add the following enetries.

authentication.visible=true

authentication.default=secEnterprise

cms.visible=true

3. Restarted tomcat.

The authentication pull down is not displaying. Do I have to redeply the war files? If yes, how do i do this? Or is there something else i need to do?

I am using BI 4.0 SP5 Patch 6.

Thanks,
