    ISSUE:

    Today, March 27, 2017, at 1235h PST, the Azure AD B2C monitors detected failures in authentications when Facebook was used as the identity provider. The team has discovered that Facebook has implemented a change in the method they use to send their response from the access_token endpoint. The query response method, which was expected by Azure AD B2C, has been deprecated in favor of a JSON -formatted response.



    FIX: The Azure AD B2C team has RESOLVED the issue for 100% of our impacted Azure AD B2C Standard customers.



    NOTE: A few tenants using some advanced private preview features (less than 5% of our total) with policies of the format B2C_1A_name must make a few manual changes to their policies that use Facebook. We will publish these changes shortly. These customers may reach out to us at [email protected] with questions.
