Use this guide along with the Data Tab Configuration guide to configure a SecureAuth IdP realm that uses Web Service (Multi-Data Store) as an additional Profile Provider.
Web Service enables SecureAuth IdP to access multiple data stores to extract the appropriate user information for authentication and assertion.
1. Have on-premises data stores (Active Directory, SQL Server, ODBC, etc.)
2. Service accounts with read access (and optional write access) for SecureAuth IdP for each data store
