Hi,
Sometimes an existing user of our portal is prompted to enter an email address after it's login.
and this is failing because the email already exists in the Dataverse contact table.
but the contact exists in dataverse, the email is the right one, the Azure B2C account is correctly related to this contact, the user was able to connect in the past.
it's just that 1 day, this stop working for him.
I have not identified when and why this problem occurred.
there is certainly a solution so "repair" the missing information in dataverse, I'm just not able to find which table may have missing information.
outside the adx_external_identity and contact tables, which ones are involved in the login process and may have missing info?
is there any log available which can describe the errors suffered in the system during the login process?
for now, I have to delete the user in Azure B2C and ask my customer to recreate a new user there.
