Azure AD B2C sign-in policy

Question

Scenario: Our On-premise AD currently holds our customers/users for on-premise apps.

We starting developing cloud apps for our customers/users and looking at Azure AD/Azure AD B2C for identity management.

We want to use ad connect sync with pass-through authentication to Azure AD because of security requirements.

Customers/users have usernames in form of [email protected] in the on-premise - not [email protected]. That means when AD connect sync to Azure AD the username becomes [email protected] and name [email protected].

The Azure AD we sync to is a Azure AD B2C directory.

Question: Is it possible to edit the Azure AD B2C sign-in policy to use name ([email protected]), not username ([email protected]) and password?

Answer 1

You cannot use Azure AD B2C sign-in policy to change the synced user name and password.

First, the synced users are in Azure AD, not Azure AD B2C.

Azure AD Connect is not designed to work with Azure AD B2C

Second, if you still want synced username to match your on-premise username, you can refer to this article .

Also,if you have not synced from Azure AD Connect, you can use custom settings in Azure AD Connect to let synced username match your on-premise username.
