azure - Azure AD B2C 中的 Access_denied 资源所有者密码凭据流

Question

我按照下面的这篇文章进行操作，但在“测试用户流程”部分中收到了以下错误:

https://learn.microsoft.com/en-gb/azure/active-directory-b2c/configure-ropc

HTTP/1.1 400 Bad Request
Cache-Control: private
Content-Type: application/json; charset=utf-8

{"error":"access_denied","error_description":"AADB2C90225: The username or password provided in the request are invalid.\r\nCorrelation ID: 9b3c19e2-6084-4bcd-b7d3-aab8d2c34dd9\r\nTimestamp: 2019-01-30 13:35:09Z\r\n"}

请求已发送:

POST https://mytenant.b2clogin.com/mytenant.onmicrosoft.com/oauth2/v2.0/token?p=B2C_1_ROPC_Auth HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Host: mytenant.b2clogin.com

username=myemail&password=password&grant_type=password&scope=openid myappId offline_access&client_id=myappId&response_type=token+id_token

我是全局管理员，但我能够创建用户流程、注册应用程序等。

我使用Fiddler发送请求，所以与WebApp/WebAPI无关。

用户名(例如 [email protected] )和密码正确，用于登录 azure 门户来设置示例。

有什么想法吗？

更新

请注意，我使用的用户是我公司事件目录中的用户角色，但该用户是与 https://learn.microsoft.com/en-gb/azure/active-directory-b2c/tutorial-create-tenant 之后新创建的 AD B2C 租户关联的事件目录中的全局管理员。

Answer 1

基本上，如果您遵循文档 here 。您将收到此错误消息，因为步骤 4 中的说明错误。

在您的 TrustFrameworkExtensions 文件中。您的本地帐户登录声明提供者 -> TechnicalProfiles 中应该有类似的内容

<TechnicalProfile Id="ResourceOwnerPasswordCredentials-OAUTH2">
    <DisplayName>Local Account SignIn</DisplayName>
    <Protocol Name="OpenIdConnect" />
    <Metadata>

        <InputClaim ClaimTypeReferenceId="client_id" DefaultValue="{Proxy-Identity-Experience-Framework-ClientId}" />
        <InputClaim ClaimTypeReferenceId="resource_id" PartnerClaimType="resource" DefaultValue="{Identity-Experience-Framework-ClientId}" />
    </InputClaims>
    <OutputClaims>
        <OutputClaim ClaimTypeReferenceId="objectId" PartnerClaimType="oid" />
        <OutputClaim ClaimTypeReferenceId="userPrincipalName" PartnerClaimType="upn" />
    </OutputClaims>

        <OutputClaimsTransformation ReferenceId="CreateSubjectClaimFromObjectID" />
    </OutputClaimsTransformations>

</TechnicalProfile>

请注意，resource_id 应为 IdentityExperienceFramework 应用程序(客户端)Id，而不是 Microsoft 文档中所述的 ProxyIdentityExperienceFramework。我已在 GitHub 中提交了纠正此问题的请求。
