SubjectConfirmationData中的收件人與當前URL不匹配

Question

嘗試連接到Webseal SAML端點時出現以下錯誤

我的服務器設置為SP，我正在嘗試對在saml20-idp-remote.php中設置的IDP進行身份驗證

重定向正常運行，但是當IDP重定向回我的SP時，出現以下錯誤。

SimpleSAML_Error_Error: UNHANDLEDEXCEPTION
Backtrace:

Caused by: SimpleSAML_Error_Exception: Error validating SubjectConfirmation in Assertion:

如何更改配置文件中主題確認數據中的收件人URL。

我的配置文件如下。

'default-sp' => array(
    'saml:SP',

    // The entity ID of this SP.
    // Can be NULL/unset, in which case an entity ID is generated based on the metadata URL.
    'entityID' => 'http://local.com/',

    // The entity ID of the IdP this should SP should contact.
    // Can be NULL/unset, in which case the user will be shown a list of available IdPs.
    'idp' => 'https://example.com/federatedaccess/SSOConsume.do',

    // The URL to the discovery service.
    // Can be NULL/unset, in which case a builtin discovery service will be used.
    'discoURL' => null,
    'privatekey' => 'saml.pem',
    'certificate' => 'saml.crt',
)

SAML2.0 Idp遠程配置

$metadata['https://example.com/federatedaccess/SSOConsume.do'] = array(
  'name' => array(
    'en' => 'My SSO',
  ),
  'description' => 'My single sign on webseal environment.',
  'ForceAuthn' => false,
  'IsPassive' => false,
  'ProtocolBinding' => 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST',
  'SingleSignOnService' => 'https://example.com/federatedaccess/SSOConsume.do',
  'certificate' => 'pub.crt',
  'sign.authnrequest' => true,
  'redirect.sign' => true,
  'redirect.validate' => true,
);

干杯

這是如何通過SP配置IdP的問題。 應該將SubjectConfirmationData的Recipient設置為http://example.com/simplesaml/module.php/saml/sp/saml2-acs.php/default-sp ，而應使用http://example.com/simplesaml/module.php/saml/sp/metadata.php/default-sp （注意saml2-acs.php與meta.php的區別）。

Idp使用的URL是檢索SP的元數據的URL。 似乎不是讀取元數據，而是使用該URL作為AssertionConsumerService URL。
