In a previous version of the PHP SDK there was the ability in an App to get the Profile ID of the user that owned the page where the app was installed.
$facebook->get_profile_user()
This was possible without having the end user authorize access to the Facebook App.
However I can’t find anything similar in the new JS or Graph API’s. The closest thing I could find was the https://graph.facebook.com/<page_id>/admins, however it seems this call either doesn’t work, or requires addition permissions:

Graph API: /210093142392039/admins
$this->facebook->api('/291231207559006/admins')
( ! ) Fatal error: Uncaught OAuthException: (#210) Subject must be a page. thrown in /html/classes/facebook/base_facebook.php on line 1033
Is this functionality gone? We were using the Profile ID as a key in a datasource, so it’d be ideal to keep this same key, if not we can start storing the page-id instead, however this would the users would have to reinitialize the app..
After September 22, 2011, manage_pages permission is required to do that.
You must request for the manage_pages permission, get the page access_token and then make the admins request with the page access_token.
Please refer to http://developers.facebook.com/docs/reference/api/permissions/ for updated permissions.
