Enable Multi-Factor Authentication for AD Connector

You can enable multi-factor authentication for your AD Connector directory by performing the following procedure. For more information about using multi-factor authentication with AWS Directory Service, see AD Connector Prerequisites.

Note

Multi-factor authentication is not available for Simple AD. However, MFA can be enabled for your AWS Managed Microsoft AD directory. For more information, see Enable Multi-Factor Authentication for AWS Managed Microsoft AD.

To enable multi-factor authentication for AD Connector

  1. In the AWS Directory Service console navigation pane, select Directories.

  2. Choose the directory ID link for your AD Connector directory.

  3. Select the Networking & security tab.

  4. In the Multi-factor authentication section, choose Actions, and then select Enable.

  5. On the Enable multi-factor authentication (MFA) page, provide the following values:

    Display label

    Provide a label name.

    RADIUS server DNS name or IP addresses

    The IP addresses of your RADIUS server endpoints, or the IP address of your RADIUS server load balancer. You can enter multiple IP addresses by separating them with a comma (e.g., 192.0.0.0,192.0.0.12).

    Note

    RADIUS MFA is applicable only to authenticate access to the AWS Management Console, or to Amazon Enterprise applications and services such as Amazon WorkSpaces, Amazon QuickSight, or Amazon Chime. AWS Directory Service does not support RADIUS Challenge/Response authentication. Users must have their MFA code at the time they enter their username and password. Alternatively, you must use a solution that performs MFA out-of-band such as SMS text verification for the user.

    Port

    The port that your RADIUS server is using for communications. Your on-premises network must allow inbound traffic over the default RADIUS server port (UDP:1812) from the AWS Directory Service servers.

    Shared secret code

    The shared secret code that was specified when your RADIUS endpoints were created.

    Confirm shared secret code

    Confirm the shared secret code for your RADIUS endpoints.

    Protocol

    Select the protocol that was specified when your RADIUS endpoints were created.

    Server timeout (in seconds)

    The amount of time, in seconds, to wait for the RADIUS server to respond. This must be a value between 1 and 50.

    Max RADIUS request retries

    The number of times that communication with the RADIUS server is attempted. This must be a value between 0 and 10.

    Multi-factor authentication is available when the RADIUS Status changes to Enabled.

  6. Choose Enable.
