How to pass and validate the signInEmail claim during External IDP login using Azure B2C custom policy?
问题 This question is related to this one. What we'd like to do is: at the moment the user clicks the button like Facebook OR Microsoft account OR Corporate AD in the Sign in page, call a validation technical profile to validate the email address the user is using to sign in. I tried adding an OrchestrationStep like this: <OrchestrationStep Order="4" Type="ClaimsExchange"> <Preconditions> <Precondition Type="ClaimEquals" ExecuteActionsIf="false"> <Value>idp</Value> <Value>CorporateAD</Value>
