SimpleSAMLPHP: because it isn't a valid IdP for this SP

Question

i am getting the following error when i am redirecting back from idp to saml-sp.

SimpleSAML_Error_Error: UNHANDLEDEXCEPTION
Backtrace:
0 /var/simplesamlphp/www/module.php:180 (N/A)
Caused by: SimpleSAML_Error_Exception: Cannot retrieve metadata for IdP 'https://openidp.feide.no' because it isn't a valid IdP for this SP.

I tried to change metadata 'https://openidp.feide.no' to 'http://192.168.0.105:81'. But still the issue is not resolved. Could someone suggest any idea to resolve it?

Answer 1

There should be an entry like following inside metadata/saml20-idp-remote.php file for the 'issuer' value coming inside the SAMLResponse:

$metadata['https://openidp.feide.no'] = array( <config data removed for brevity> );

Also, within config/authsources.php you should point to that 'issuer' value inside your respective SP's configuration.

'sp1' => array(
        'idp' => 'https://openidp.feide.no', 
         <other config data removed for brevity>
),
