Configuring Source Attribute Mapping for Email Aliases

To ensure seamless integration with Single Sign-On (SSO) systems, it's crucial to correctly configure the mapping of source attributes. This configuration allows the use of an email alias instead of the actual mailbox address for SSO authentication.

For instance, consider you're employing [email protected] as the alias and [email protected] as the primary mailbox address. In this scenario, the configuration on the Azure platform should map the source attribute to the alias ([email protected]), not to the mailbox ([email protected]).

For a full list of user profile attributes in Azure Active Directory B2C, refer to the Microsoft documentation here.

This setup is vital for aligning with Azure's user profile configuration requirements for aliases and mailbox addresses.

b. first_name

c. last_name
