What are you trying to do?

I am trying to find a way to configure Multiple IDP with one SP. Right now we have 1 IDP running with simplesamlSAMLPHP as SP. on a subdomain like http://sso.WEBSITE.com/
Do need to setup another subdomain in order to add a new IDP and redeploy the simplesamlphp there? Or I can add another IDP to the same SP?

What have you done?

I have an SSO system setup using simplesamlphp-1.14.11, which at the moment serving as SP to 1 IDP. As show in the code below:

=====authsources.php========
<?php
$config = array (
    'admin' => array (
        ''
    ),
    'default-sp' => array (
        'saml:SP',
        'entityID' => null,
        'idp' => 'https://SOME_IDP_URL',
        'discoURL' => null
    )
);
=========================


=====saml20-idp-remote.php=====
<?php
$metadata['https://SOME_IDP_URL'] = array (
  'entityid' => 'https://SOME_IDP_URL',
  'contacts' => array (  ),
  'metadata-set' => 'saml20-idp-remote',
  'SingleSignOnService' => array (),
  'SingleLogoutService' => array (),
  'ArtifactResolutionService' => array (),
  'NameIDFormats' => array (),
  'keys' => array (
    0 => array (),
    1 => array (),
  ),
);
===========================


Any help on this would be much appreciated!

Hi it is possible if IdP are not on same installation of SSP.
On other hand maybe that is issue in original code of SSP, which i discover few days ago.
