如何在AD B2C中预先创建“商业客户”

问题描述 投票:0回答:1

我正在建立一个入门的webapp来为我的LOB应用程序配置用户。我的大多数客户都是“商业客户”,这意味着他们通常会通过自定义策略定向到v1公共端点,允许他们对自己的AAD租户进行身份验证。挑战是新用户还需要在LOB应用程序中进行后续配置(创建数据库用户,分配一些权限等)。

作为入职的一部分,我想做的是调用graphAPI来创建将成为b2c中的联合用户帐户,然后使用新用户objectId返回处理特定于我的LOB应用程序的后续设置。理想情况下,当用户第一次到达时,他们将被重定向到针对他们自己的AAD的身份验证,然后映射到b2c中的预先创建的用户,最后使用已经配置并准备好的objectId登陆LOB应用程序。

这是一个支持的方案,有一些创意使用自定义策略和graphAPI?

谢谢马克

您有以下选项:

  1. 使用外部电子邮件地址创建本地帐户用户,并将外部用户标识与此本地帐户用户链接。
  2. 使用外部用户标识创建外部帐户用户。

1.使用外部电子邮件地址创建本地帐户用户

使用Azure AD Graph API,您可以使用create a local account user,并将用户对象的signInNames属性设置为外部用户的电子邮件地址:

{
  "accountEnabled": false,
  "creationType": "LocalAccount",
  "displayName": "John Smith",
  "passwordProfile": {
    "password": "a-strong-random-password",
    "forceChangePasswordNextLogin": false
  }
  "signInNames": [
    {
      "type": "emailAddress",
      "value": "[email protected]"
    }
  ]
}

注意:我建议将用户对象的accountEnabled属性设置为true,以便最终用户无法使用本地帐户密码登录。

使用自定义策略,您可以添加新逻辑以使用外部电子邮件地址查找本地帐户用户,并将外部用户身份添加到此本地帐户用户,例如:

2.使用外部用户标识创建外部帐户用户

使用Azure AD Graph API,可以将create an external account user与用户对象的userIdentities属性设置为外部用户的对象标识符:

{
  "accountEnabled": false,
  "displayName": "John Smith",
  "mailNickname": "john.smith",
  "otherMails": [
    "[email protected]"
  ],
  "userIdentities": [
    {
      "issuer": "https://sts.windows.net/{their-tenant-object-id}/",
      "issuerUserId": "{their-user-object-id}"
    }
  ],
  "userPrincipalName": "{guid}@{your-tenant-name}.onmicrosoft.com"
}

其中issuerUserId必须设置为外部用户的对象标识符的base64编码。

注意:在Azure AD OpenID Connect技术配置文件中,您可能必须将socialIdpUserId声明的声明映射从子声明更改为oid声明,以便它与用户对象的userIdentities.issuerUserId属性匹配:

<OutputClaim ClaimTypeReferenceId="socialIdpUserId" PartnerClaimType="oid" />
