saml - Shibboleth名称ID格式的电子邮件地址

我正在将SAML供应商（Freshdesk）集成到我的Shibboleth环境中。我的问题是nameID格式为空。

通读我供应商的文档，他们想要<saml:NameID Format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress">[email protected]</saml:NameID>

我已将此格式添加到我的元数据中，以及电子邮件的属性定义中的属性编码器中。

但是，在调试日志中，我收到此消息：

我一直无法找到AddNameIDToSubjects错误的原因，为什么将NameID留空？我的属性编码器有问题吗？

 <resolver:AttributeDefinition id="email" xsi:type="ad:Simple"
              sourceAttributeID="mail" >
        <resolver:Dependency ref="psdldap" />


        <resolver:AttributeEncoder
                xsi:type="enc:SAML2StringNameID"
                xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
                nameFormat="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" />

        <resolver:AttributeEncoder
                xsi:type="enc:SAML1String"
                name="urn:mace:dir:attribute-def:email"/>
        <resolver:AttributeEncoder
                xsi:type="enc:SAML2String"
                nameFormat="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"
                name="urn:oid:0.9.2342.19200300.100.1.3" friendlyName="email"/>
    </resolver:AttributeDefinition>

最佳答案

SAML2AttributeSourcedGenerator应该在saml-nameid.xml中配置

<!-- SAML 2 NameID Generation -->
<util:list id="shibboleth.SAML2NameIDGenerators">

    <ref bean="shibboleth.SAML2TransientGenerator" />

    <!-- Uncommenting this bean requires configuration in saml-nameid.properties. -->
    <!--
    <ref bean="shibboleth.SAML2PersistentGenerator" />
    -->

    <bean parent="shibboleth.SAML2AttributeSourcedGenerator"
        p:format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"
        p:attributeSourceIds="#{ {'email'} }" />

</util:list>
