I want to do a post on the wall of a fan page on facebook. (/me/feed)
I modified the module facebook.js adding 'manage_pages' scope and method '/ me / accounts'.
In the session token is stored on the user and not the fan page.
With the method '/ me / accounts' get the token to manage the fan page, but I can not change the access token that is stored in the session hello.js, this is the token for the user and not the fan page.
Is possible to change the user token by token fan page?

thank you very much
regards
