 To use an Azure Active Directory (Azure AD) as an [identity provider](authorization-code-flow.md) in Azure AD B2C, you need to create an application that represents it. This article shows you how to enable sign-in for users from a specific Azure AD organization using a user flow in Azure AD B2C.
 
-## Create an Azure AD app

-To enable sign-in for users from a specific Azure AD organization, you need to register an application within the organizational Azure AD tenant, which is not the same as your Azure AD B2C tenant.

-
-    **Do not** use the Azure AD v2.0 metadata endpoint, for example `https://login.microsoftonline.com/contoso.onmicrosoft.com/v2.0/.well-known/openid-configuration`.
