For several case types / entities, additional data is being displayed in IFRAMEs inside the CRM pages. This data is partially based on CRM stuff and partially comes from additional data sources associated with a CRM entity.
Edit: The IFRAME content is located on another server.
The question is: How can I use CRM as a session and role provider so, that the ASP page inside the IFRAME can 'ask' CRM whether the current user is logged on to CRM and allowed to see the data (based on the access-right etc. associated with the case).
Can you give me a hint where to search? (I'm new to this topic.)
