saml - 使用 ADFS IdP 进行单点注销的正确注销请求

Question

我成功地将 OneLogin java-saml 库用于 SAML SSO。但是，Active Directory 联合身份验证服务 (ADFS) 的 SLO(单点注销)存在问题。库创建的 LogoutRequest 被 ADFS 拒绝，而 SimpleSAMLphp IdP 接受它。我在 LogoutRequest 创建时在响应中传递从 ADFS 收到的 nameId 和 sessionIndex。

以下是生成的请求和收到的响应:

身份验证请求:

ADFS上出现的错误是: The SAML Single Logout request does not correspond to the logged-in session participant. 带有额外的错误描述:

User Action 
Verify that the claim provider trust or the relying party trust configuration is up to date. If the name identifier in the request is different from the name identifier in the session only by NameQualifier or SPNameQualifier, check and correct the name identifier policy issuance rule using the AD FS Management snap-in.

应该在 LogoutRequest 中修改什么才能使注销发生？

Answer 1

好的，问题解决了。

正如您在 SAML 响应中看到的，我发布了 NameID 元素没有 Format 属性:

<Subject>
     <NameID>hamilton1@mycompany.test</NameID>
     ...
</Subject>

因此，ADFS 预计 LogouRequest 中也不存在 Format 属性。
以下 LogoutRequests 导致成功注销:

<samlp:LogoutRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" ID="ONELOGIN_947f5e64-8423-4464-b4b0-fa416dfe62a0" Version="2.0" IssueInstant="2017-05-31T15:43:18Z" Destination="https://wintest.mycompany.test/adfs/ls/">
   <saml:Issuer>http://localhost:4568/sso/saml/metadata</saml:Issuer>
   <saml:NameID>hamilton1@mycompany.test</saml:NameID>
   <samlp:SessionIndex>_6f6daef8-f0b5-4437-8e35-ae44ffc48cfe</samlp:SessionIndex>
</samlp:LogoutRequest>

如果我更改声明发布策略以使用以下规则将名称 ID 映射到 ADFS 中的电子邮件地址:

c:[Type == "http://schemas.microsoft.com/ws/2008/06/identity/claims/windowsaccountname", Issuer == "AD AUTHORITY"]
 => issue(store = "Active Directory", types = ("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress"), query = ";mail;{0}", param = c.Value);

c:[Type == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress"]
 => issue(Type = "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier", Issuer = c.Issuer, OriginalIssuer = c.OriginalIssuer, Value = c.Value, ValueType = c.ValueType, Properties["http://schemas.xmlsoap.org/ws/2005/05/identity/claimproperties/format"] = "urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress");

我收到以下 SAML 响应:

<Subject>
     <NameID Format="urn:oasis:names:tc:SAML:2.0:nameid-format:emailAddress">hamilton1@mycompany.test</NameID>
     ...
</Subject>

发送 LogutRequest 和 <NameID Format="urn:oasis:names:tc:SAML:2.0:nameid-format:emailAddress"> 注销成功:

我正在使用 2.0.1 版的 java-saml，所以我在 Java 中执行以下操作，因为 LogoutRequest 没有接受 nameIdFormat 的构造函数: https://github.com/onelogin/java-saml/blob/v2.0.1/core/src/main/java/com/onelogin/saml2/logout/LogoutRequest.java :

LogoutRequest logoutRequest = new LogoutRequest(settings, null, nameId, sessionIndex);
String samlRequestXml = logoutRequest.getLogoutRequestXml();
samlRequestXml = samlRequestXml.replaceAll(" Format=\".+\"", "");

计划添加接受 LogoutRequest 作为参数的 nameIdFormat 构造函数。 https://github.com/onelogin/java-saml/issues/98 中有更多细节。
