    1. In the Admin Console, go to DirectoryGroups.
    2. Click Add Group.
    3. Complete the fields and then click Save.
    4. Add people to the group. See Users, groups, and profiles.

    4. Search for and select Microsoft ADFS (MFA), and then click Add Integration.

        Ensure that the redirect URI ends with a forward slash. For example, https://yourdomain.com/

      2. Go to the Sign on tab of the new Microsoft ADFS app instance and confirm that the sign-on mode is OpenID Connect.

      For Okta orgs that aren't enabled for OpenID Connect and Single Sign-On:

      1. Go to the Sign On tab and ensure that MFA as a service is selected.
    7. Go to the General tab and note the values of the Client ID and Client secret. These values are required during the Install the Okta ADFS Plugin on your ADFS Server task.
