Question

我下载了WSO2 IS版本5.9.0。我按照此处https://is.docs.wso2.com/en/5.9.0/learn/adding-and-configuring-an-identity-provider/的建议配置了一个外部IDP，然后配置了声明和要在其中使用SAML2 SSO的服务提供商。

我配置了服务提供商，以便在登录过程中使用高级配置，其中第一步是基本身份验证，而步骤2是通过使用我的外部IDP完成的。

当我在WSO2 IS 5.9.0中遇到很多问题时，相同的配置在WSO2 5.8.0中效果很好。

在5.9.0版本中，当我尝试登录到我的应用程序时，WSO2向我显示登录界面，但是当我通过外部IDP单击登录时，弹出窗口为空，如图所示

此外，我注意到当我尝试这样修改$ {WSO2_IS_HOME} / repository / conf / identity中的application-authentication.xml时，我的修改丢失了，并且文件返回到默认状态。我试图在Deployment.toml中插入修改，但是我不知道如何正确配置SAMLSSO。

然后，我仅通过显示外部登录界面来尝试配置服务提供者。我得到一个错误。堆栈跟踪如下：

通过调试，似乎在方法org.wso2.carbon.context.internal.CarbonContextDataHolder中的类endTenantFlow()中，我们尝试从一个空堆栈中弹出，如下面的代码所示：

public void endTenantFlow() {
    Stack<CarbonContextDataHolder> carbonContextDataHolders = parentContextHolderStack.get();
    if (carbonContextDataHolders != null) {
        currentContextHolder.set(carbonContextDataHolders.pop());
    }
}

此代码来自jar org.wso2.carbon.utils-4.5.1.jar

您有小费吗？在我看来，这是一个错误，但这是一个显而易见的问题。...

Answer 1

我想我找到了错误。

在构造函数的org.wso2.carbon.identity.application.authenticator.samlsso.manager.X509CredentialImpl类中，有这段代码：

try {
    /**
     * Get the private key and the cert for the respective tenant domain.
     */
    if (!tenantDomain.equals(MultitenantConstants.SUPER_TENANT_DOMAIN_NAME)) {
        FrameworkUtils.startTenantFlow(tenantDomain);
        //Do some stuffs
    } else {
        //Do other stuffs
    }
} catch (Exception e) {
    //Handle exception
} finally {
    FrameworkUtils.endTenantFlow();
}

如您所见，FrameworkUtils.startTenantFlow(tenantDomain);仅在第一个if为true时才被调用。这意味着，最后我们必须正确处理endTenantFlow（）。我以这种方式修改了代码：

try {
    /**
     * Get the private key and the cert for the respective tenant domain.
     */
    if (!tenantDomain.equals(MultitenantConstants.SUPER_TENANT_DOMAIN_NAME)) {
        FrameworkUtils.startTenantFlow(tenantDomain);
        //Do some stuffs
    } else {
        //Do other stuffs
    }
} catch (Exception e) {
    //Handle exception
} finally {
    if (!tenantDomain.equals(MultitenantConstants.SUPER_TENANT_DOMAIN_NAME)) {
        if (log.isDebugEnabled()) {
            log.debug("finalizzo il tenant flow per tenant domain " + tenantDomain);
        }
        FrameworkUtils.endTenantFlow();
    } else {
        if (log.isDebugEnabled()) {
            log.debug("Tenant domain " + tenantDomain + " nessun flow da finalizzare");
        }
    }
}

现在看来可以正常工作

我希望它会有用
