Configure SAML single sign-on with Google

You can configure your ExtraHop system to enable users to log in to the system through the Google identity management service.

Before you begin

  • You should be familiar with administrating Google Admin.
  • You should be familiar with administrating ExtraHop systems.

These procedures require you to copy and paste information between the ExtraHop Admin UI and the Google Admin UI, so it is helpful to have each UI open side-by-side.

  1. Log in to the Administration page on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
  2. In the Access Settings section, click Remote Authentication.
  3. From the Remote authentication method drop-down list, select SAML.
  4. Click Continue.
  5. Click View SP Metadata.
  6. Copy the ACS URL and Entity ID to a text file. You will paste this information into the Google configuration in a later procedure.

  2. Click the Enable SSO for a SAML application icon .

  11. Choose how you would like to provision users from one of the following options.
    • Select Auto-provision users to create a new remote SAML user account on the ExtraHop system when the user first logs in to the appliance.
    • Clear the Auto-provision users checkbox and manually configure new remote users through the ExtraHop Admin UI or REST API. Access and privilege levels are determined by the user configuration in Google.
  12. The Enable this identity provider option is selected by default and allows users to log in to the ExtraHop system. To prevent users from logging in, clear the checkbox.
  13. Configure user privilege attributes. You must configure the following set of user attributes before users can log in to the ExtraHop system through an identity provider. Values are user-definable; however, they must match the attribute names that are included in the SAML response from your identity provider. Values are not case sensitive and can include spaces. For more information about privilege levels, see Users and user groups..
    Important:You must specify the attribute name and configure at least one attribute value other than No access to enable users to log in.
    In the example below, the Attribute Name field is the application attribute and the Attribute Value is the user field name configured when creating the ExtraHop application on the identity provider.
