Webdynpro application with Password Protection

Hi Experts,

We are implementing SPNEGO with SAP EP 7.4 SP 8 but one challenge in this scenario is to make ESS/MSS applications password protected after SPNEGO.

Once User will logged into Portal through SPNEGO, he/she should be able to access ESS/MSS application with Password.

So all this applications should be password protected.

How can we achieve this ?

Please suggest ASAP.

Regards,
