I'm using Azure AD B2C Local Accounts Sign-in with custom policies. Is there a way to intercept the username entered before validation, modify it and then continue with validation with the modified name?
I am using a single tenant for multiple organizations and by concatenating organization with username i want to create a uniqueness to resolve more then 1 user from 2+ organizations having the same username.
looking at Transform username in Azure AD B2C authentication did not help, am I missing something?
Thank you
