基于SAML和Laravel的SSO

Question

我正在为一个php web应用程序实现基于SAML的SSO。我在用谷歌做IDP。我使用了Laravel 5- Saml2插件，并按照文档中给出的步骤进行了配置。我还在谷歌管理控制台中添加了这个应用程序，作为SAML应用程序，使用给定的这里步骤，并在saml2_settings.php中配置entityId和acs。但是，我无法配置x509cert证书。当我点击登录url时，用户将被重定向到google进行身份验证，但是当我输入凭据时，它不会返回应用程序并给出以下错误：

1. 这是个错误。

错误: app_not_configured_for_user

服务未为此用户配置。

以下是我的saml2_settings文件：

'sp' => array(

    // Specifies constraints on the name identifier to be used to
    // represent the requested subject.
    // Take a look on lib/Saml2/Constants.php to see the NameIdFormat supported
    'NameIDFormat' => 'urn:oasis:names:tc:SAML:2.0:nameid-format:persistent',

    // Usually x509cert and privateKey of the SP are provided by files placed at
    // the certs folder. But we can also provide them with the following parameters
    'x509cert' => 'I ADDED x509certs here which I downloaded from google',
    'privateKey' => '',

    //LARAVEL - You don't need to change anything else on the sp
    // Identifier of the SP entity  (must be a URI)
    'entityId' => 'snipeit', //LARAVEL: This would be set to saml_metadata route
    // Specifies info about where and how the <AuthnResponse> message MUST be
    // returned to the requester, in this case our SP.
    'assertionConsumerService' => array(
        // URL Location where the <Response> from the IdP will be returned
        'url' => 'http://dev.sb.com/snipeit/public/account/profile', //LARAVEL: This would be set to saml_acs route
        //SAML protocol binding to be used when returning the <Response>
        //message.  Onelogin Toolkit supports for this endpoint the
        //HTTP-Redirect binding only
        'binding' => 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST',
    ),
    // Specifies info about where and how the <Logout Response> message MUST be
    // returned to the requester, in this case our SP.
    'singleLogoutService' => array(
        // URL Location where the <Response> from the IdP will be returned
        'url' => '', //LARAVEL: This would be set to saml_sls route
        // SAML protocol binding to be used when returning the <Response>
        // message.  Onelogin Toolkit supports for this endpoint the
        // HTTP-Redirect binding only
        'binding' => 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect',
    ),
),

// Identity Provider Data that we want connect with our SP
'idp' => array(
    // Identifier of the IdP entity  (must be a URI)
    'entityId' => '',
    // SSO endpoint info of the IdP. (Authentication Request protocol)
    'singleSignOnService' => array(
        // URL Target of the IdP where the SP will send the Authentication Request Message
        'url' => $idp_host,
        // SAML protocol binding to be used when returning the <Response>
        // message.  Onelogin Toolkit supports for this endpoint the
        // HTTP-POST binding only
        'binding' => 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect',
    ),
    // SLO endpoint info of the IdP.
    'singleLogoutService' => array(
        // URL Location of the IdP where the SP will send the SLO Request
        'url' => $idp_host . '/saml2/idp/SingleLogoutService.php',
        // SAML protocol binding to be used when returning the <Response>
        // message.  Onelogin Toolkit supports for this endpoint the
        // HTTP-Redirect binding only
        'binding' => 'urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect',
    ),
    // Public x509 certificate of the IdP
    'x509cert' => 'SAME CERTIFICATES I ADDED HERE AS WELL',        /*
     *  Instead of use the whole x509cert you can use a fingerprint
     *  (openssl x509 -noout -fingerprint -in "idp.crt" to generate it)
     */
    // 'certFingerprint' => '',
),

有人能帮帮我吗。

Answer 1

‘'sp’=>数组( 'x509cert‘=>’我在这里添加了从谷歌下载的x509certs，privateKey‘=>’，

您使用Google作为IdP，那么，为什么在sp部分使用google公共证书呢？

如果您计划对SP发送的SAML消息进行签名，那么您需要将您自己的证书/私钥放在那里。可以使用以下工具生成自签名证书：certs.php

如果您对某些设置字段有疑问，请查看Lavarel插件的文档，还可以查看插件使用的php-saml文档工具包。

为了调试正在发生的事情，我还建议您使用浏览器扩展来记录SAML消息，例如使用SAML示踪器并检查将通知您可能出现的错误的响应状态。
