Authentication Missing in AIX server -BI Launchpad

Dear Experts,

We are using BI BO 4.0 SP8 in AIX Server.But while login to BI launchpad,We couldn't able to see the Authentication option to login with SAP BI credentials in BI Launchpad.

Please suggest the path in AIX server to do changes for Launchpad properties to enable Authentication option.

Thanks & Regards,
