.net wsFederationHttpBinding，将自定义用户标识传递给STS

我正在尝试实现以下场景：

客户将其证明文件交给医生

STS应用自定义授权策略来确定特定用户可用的声明集，并发布安全令牌

客户端将令牌传递给业务服务，业务服务根据用户从令牌获得的声明集确定用户的权限

看来第一步是主要问题。正如所建议的，wsFederationHttpBinding的消息元素没有clientCredentialsType。因此，每当我的AuthorizationPolicy检查evaluationContext.Properties[“Identity”]时，它都会在其中看到WindowsIdentity。我想根据自定义存储（DB）对用户进行身份验证

---

有没有办法通过wsFederationHttpBinding来实现这一点？

好吧，下面是答案

STS配置：

<behaviors>
     <serviceBehaviors>
         <behavior name="STSBehaviour">
             <!--Custom credentials processing-->
             <serviceCredentials>
                 <userNameAuthentication userNamePasswordValidationMode="Custom" 
                                         customUserNamePasswordValidatorType="SecurityTokenService.UserNameValidator, SecurityTokenService"/>
             </serviceCredentials>
             <!--------------------------------->
         </behavior>
    </serviceBehaviors>
</behaviors>
<bindings>
    <wsHttpBinding>
        <binding name="wsHttpUsername">
            ...
            <security mode="Message">
                <message clientCredentialType="UserName"
                         negotiateServiceCredential="false"
                         establishSecurityContext="false" />
            </security>
            ...
        </binding>
    </wsHttpBinding>
</bindings>
<services>
    <service behaviorConfiguration ="STSBehaviour"
               name="Microsoft.ServiceModel.Samples.SecurityTokenService" >
           ....
    </service>
</services>

public class UserNameValidator : UserNamePasswordValidator
{
    public override void Validate(string userName, string password)
    {
        if (!VerifyCredentials(userName, password))
            throw new SecurityException("Invalid credentials");
    }
}
