Roles created by Azure extension for SQL Server installation

Applies to: SQL Server

This article lists the server and database roles and mappings that the installation of Azure extension for SQL Server creates.

Roles

When you install Azure extension for SQL Server, the installation:

  1. Creates a server level role: SQLArcExtensionServerRole

  2. Creates a database level role: SQLArcExtensionUserRole

  3. Adds NT AUTHORITY\SYSTEM* account to each role

  4. Maps NT AUTHORITY\SYSTEM* at the database level for each database

  5. Grants minimum permissions for the enabled features

    *Alternatively, you can configure SQL Server enabled by Azure Arc to run in least privilege mode (available in preview). For details, review Operate SQL Server enabled by Azure Arc with least privilege (preview).

In addition, Azure extension for SQL Server revokes permissions for these roles when they're no longer needed for specific features.

SqlServerExtensionPermissionProvider is a Windows task. It grants or revokes privileges in SQL Server when it detects:

  • A new SQL Server instance is installed on the host
  • SQL Server instance is uninstalled from host
  • An instance level feature is enabled or disabled or settings are updated
  • Extension service is restarted

Note

Prior to the July, 2024 release, SqlServerExtensionPermissionProvider is a scheduled task. It runs hourly.

For details, review Configure Windows service accounts and permissions for Azure extension for SQL Server.

If you uninstall Azure extension for SQL Server, the server and database level roles are removed.
