How to pass user credentials from CRM 2013 to IFrames with Microstrategy dashboard

Hello all,

I want to embed IFrame which calls Microstrategy url into Dynamics CRM 2013. How to enable Single Sign On for Dynamics CRM so that the credentials are passed from CRM to Microstrategy. I don't want the user to see a new login page when they want to access Microstrategy dashboard (a BI reporting tool) inside the IFrame. Please share your experiences.

Thanks,
