SAP BI 4.1 SSO configuration for ipad

I am planning to configure SSO for Ipad to connect to BI 4.1 Sp6 systems without entering id and password.

I looked at Ashutosh`s blog.. it is very good but there are no step by step instructions.

Also noticed that it does not support windows AD authentication.

Can someone who have completed SSO on ipad on BI 4.1 platform guide me to right steps ?

Thanks in advance !
