title: How to get role permission or scope for grant_type client_credential in wso2 IS
body: <p>We have created a service provider in wso2 IS.Under <code>'Role/Permission Configuration' section</code> of that service provider we have added some custom permission.
  Is there any way for the <code>'oauth2/token'</code> call to return the permission associated with that service provider. currently we are passing the scope as <code>'openid'</code> and getting id_token in response we also want id_token along with permission values. 
  or is there any way to create scope for each service_provider and get in 'oauth2/token' response?
  <strong>Note: We are using grant_type='client_credentials' for getting id_token.</strong></p>
