By default,

Data Director

authenticates users with a SIF call to the Hub Server. For the authentication process, the MDM Hub implementation requires that you configure users to the Master Database. For more information about configuring MDM Hub users, see the

Multidomain MDM Security Guide

.

Alternatively, you can implement single sign-on (SSO) and authenticate users against with external identity providers. The Login Provider in

Data Director

communicates with the Hub Security Provider (Login Module). For more information about provider files, see the

Multidomain MDM Security Guide
