【问题描述】：

我的本地计算机上有一个 Web 应用程序：https://test.staging.me

这是 PHP (cakephp) 应用程序。

我安装了 SimpleSamlPHP 并将其配置为服务提供者 (SP)。我根据指令创建了一些测试：https://simplesamlphp.org/docs/stable/simplesamlphp-sp 我对 openidp.feide.no 的测试成功了。

但我对 OKTA 有疑问。我创建了“Test App Cakephp”并为此分配了人员并配置了 SimpleSamlPHP。

但登录后我得到了这个 SAML（没有用户属性）：

为方便起见，我删除了“ds:SignatureValue”和“ds:X509Certificate”字段。

我的问题：为什么我没有收到用户的属性？谢谢）

【解决方案1】：

默认情况下，Okta 不会在 <saml2:AttributeStatement> 中发送任何属性。要配置可选的属性语句，请查看Configuring the Okta Template SAML 2.0 App。您可以发送的五个标准 Okta 配置文件属性是名字、姓氏、电子邮件和 Okta 用户名。

对于要包含在来自 Okta 的 SAMLResponse 中的用户的名字和姓氏：

<saml2:AttributeStatement>
     <saml2:Attribute Name="FirstName" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified">
        <saml2:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">Thomas</saml2:AttributeValue>
     </saml2:Attribute>
     <saml2:Attribute Name="LastName" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:unspecified">
        <saml2:AttributeValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="xs:string">Kirk</saml2:AttributeValue>
     </saml2:Attribute>
</saml2:AttributeStatement>

您必须配置 Okta SAML 2.0 应用程序以包含以下属性声明：

FirstName|${user.firstName},LastName|${user.lastName}

除了标准的 Okta 配置文件属性（名字、姓氏、电子邮件和 Okta 用户名）之外，您还可以use additional attributes that have been pulled into Okta from Workday, Active Directory, and other LDAP directories。
