Enhanced Connector Enhanced connectors add extended capabilities and require a separate entitlement in addition to your Alation platform license.

Before installing and configuring the Purview RDBMS enhanced connector, ensure that network connectivity is in place and that you have a Microsoft Entra ID (Azure AD) service account (service principal).

Create a Microsoft Entra ID Application

Microsoft Entra ID token authentication requires a Microsoft Entra ID application registration (service principal) that Alation can use to request access tokens. See Create a Microsoft Entra application and service principal for Microsoft Purview for instructions on how to create an app registration in Microsoft Purview.

Collect the following values for configuration in Alation:

• Tenant ID — Microsoft Entra ID directory identifier.

• Client ID — application (client) ID of the app registration.

• Client secret — secret value generated during the app registration.

Permissions for Metadata Extraction

Ensure that the Microsoft Entra ID application has Purview Delegated API Access permissions.
