问题
Using AAD B2C, I'd like to enable end-users to login using their Microsoft-Live or Google identity providers (delegate the authentication). However, I have a set of custom claims in AAD B2C for my users (some roles, for example). So, once the user authenticates into google, I need to add or "map, merge" the claim set with this user's custom claims in AAD B2C and return the consolidated claim-set to my application.
My question: where can I add or map these claims in the claimset returned by AAD B2C? In some Identity Providers this is possible using filters. Not yet finding the feature in AAD B2C, pointers?
