Hi Evgeny,

"If you want embedded DSW iframe to use same   other login/password as to another application on the same web page where the user already logged in, it's the matter of how to transfer the access to an embedded iframe."

Our application calls the dashboard who belongs to BI Server, that server manage it's own users.

so we try something like this into the iframe (like the code created by the share option):
