I setup B2C sign up sign in a few weeks ago and disabled all the other identity providers for the site, this morning another developer mistakenly re-enabled local sign in and Azure Active Directory sign in. I disabled these both, but since then the B2C login is not properly functioning.
Initially when users press the sign in button in the site header they get a message saying "Sign in failed", they then press the sign in button again and get re-directed to the B2C sign in page. Signing in through the B2C sign in page then redirects to the redeem invitation section of the sign in page, if selecting the sign in button here the user is redirected back to the redeem invitation section.
Does anyone know why this would happen?
Hi @JosephPowerApps,
First please make sure that Azure Active Directory B2C is the only Identity Providers, you can double check that from the Power Pages editor -> Set Up -> Identity Providers.
Then try to disable the invitation function. Go to Site Settings -> Authentication/Registration/InvitationEnabled : Set to False.
Cheers,
Dom
