Redirect after Facebook one click login

Hello,

I have added a custom redirection for all user roles except "Administrator" to my functions.php .

function redirect_user_on_role()
{
	//retrieve current user info
	global $current_user;
     	get_currentuserinfo();
 	//If login user role is Subscriber
     	if ($current_user->user_level != 10)
     	{
        	wp_redirect( home_url()."/userbereich/" ); exit;
     	}

}
add_action('admin_init','redirect_user_on_role'

This solution seems not to work together with the one-click login ability of the Ultimate Facebook Plugin.
How can I set a redirection rule for this case?

Best
P.
