Quickstart: Connect to your Active Directory Forest

Important

Threat protection product names from Microsoft are changing. Read more about this and other updates here. We'll be updating names in products and in the docs in the near future.

In this quickstart, you'll connect Azure ATP to Active Directory (AD) to retrieve data about users and computers. If you're connecting multiple forests, see the Multi-forest support article.

Prerequisites

  • An Azure ATP instance.
  • Review the Azure ATP prerequisites article.
  • At least one of the following directory services accounts with read access to all objects in the monitored domains:
    • A standard AD user account and password. Required for sensors running Windows Server 2008 R2 SP1.

    • A group Managed Service Account (gMSA). Requires Windows Server 2012 or above.
      All sensors must have permissions to retrieve the gMSA account's password. For information about creating a gMSA account, see Set up a gMSA account.

      Note

      • For sensor machines running Windows Server 2012 and above, we recommend using a gMSA account for its improved security and automatic password management.
      • If you have multiple sensors, some running Windows Server 2008 and others running Windows Server 2012 or above, in addition to the recommendation to use a gMSA account, you must also use at least one standard AD user account.

How to set up a gMSA account

  1. Create a gMSA account.
  2. Create a new security group containing all your domain controllers with sensors (running Windows Server 2012 or above) with permissions to retrieve the gMSA account's password. (Recommended)

Provide a username and password to connect to your Active Directory Forest

The first time you open the Azure ATP portal, the following screen appears:

Azure ATP welcome stage 1

  1. Enter the following information and click Save:

    Field Comments
    Username (required) Enter the read-only AD username. For example: ATPuser. You must use a standard AD user or gMSA account. Don't use the UPN format for your username.
    Password (required for standard AD user account) For AD user account only, enter the password for the read-only user. For example: Pencil1.
    Group managed service account (required for gMSA account) For gMSA account only, select Group managed service account.
    Domain (required) Enter the domain for the read-only user. For example: contoso.com. It's important that you enter the complete FQDN of the domain where the user is located. For example, if the user’s account is in domain corp.contoso.com, you need to enter corp.contoso.com not contoso.com
  2. In the Azure ATP portal, click Download sensor setup and install the first sensor to continue.
