在工作中，我们使用ibm Cloud 区块链1.1.0，并且需要创建具有在证书中编码的属性的用户 . 不幸的是，尝试对此进行编码失败，并出现以下错

Error Code: 20 - Authorization failure

    /go/src/github.com/hyperledger/fabric-sdk-go/pkg/client/msp/client.go:374

这是我用来调用mspClient.Register的Register新用户函数体 .

// Register the new user
func (e *HfcEndpoint) RegisterUser(username string, args []string) error {
attributes := []msp.Attribute{}
// normal user with id attribute
attributes = append(attributes, msp.Attribute{
    Name: "hf.Registrar.Roles",
    Value: "validator",
    ECert: true,
})
registrationRequest := &msp.RegistrationRequest{
    Name: username,
    Type: "validator",
    Affiliation: e.orgID,
    Attributes: attributes,
}
enrollmentSecret, err := e.mspClient.Register(registrationRequest)
if err != nil {
    return errors.Wrapf(err, "Failed to register user - %s", username)
}
err = e.mspClient.Enroll(username, msp.WithSecret(enrollmentSecret))
if err != nil {
    return errors.Wrapf(err, "Failed to enroll user - %s", username)
}
return nil
}

我试图确保在此示例中仅使用管理ibm区块链创建管理员的标准属性 . 因此管理员应该能够为另一个用户编码此属性 .

(admin atributes: hf.Registrar.Roles:client,user,peer,validator,auditor)

但是我尝试了它，它失败了 . 我遵循了fabric-sdk-go的单元测试和fabric-ca的文档：

msp/enrollment_test.go

Register new Identity 1.1.0 documentation

我在文档中读到，管理员需要具有适当的属性才能将其注册给其他人 . 但是，令人困惑的是，如果我提取fabric-sdk-go单元测试中使用的管理证书，我找不到编码到用于这些测试的管理证书中的任何属性 .

我希望有人可以帮我解决如何通过fabric-sdk-go创建具有属性的用户，或者能够指出我想念的东西 . 提前致谢
