Manage Domain Mapping for Federated Authentication

On this page

  • Required Access
  • Prerequisites
  • Map a Domain to Your Identity Provider
  • Associate Your Domain with Your Identity Provider
  • Delete a Domain Mapping

You can map domains to your IdP to streamline the login experience for users from specified domains by authenticating them through an IdP. Domain mapping ensures that all users with a particular domain in their email address have the same login experience.

Important

You can map a single domain to multiple identity providers. If you do, users who log in using the MongoDB Cloud console are automatically redirected to the first matching IdP mapped to the domain.

To log in using an alternative identity provider, users must either:

  • Initiate the MongoDB Cloud login through the desired IdP, or

  • Log in using the Login URL associated with the desired IdP.

To map a domain to your IdP, you must verify that you own the domain. You can either:

  • Upload an HTML file containing a verification key to a host in your domain or

  • Create a DNS TXT record that contains a verification key.

To manage federated authentication, you must have Organization Owner access to one or more organizations that are delegating federation settings to the instance.

To complete this tutorial, you must have already linked an IdP to Atlas. To learn how to link an IdP to Atlas, see Manage Identity Providers.

1
  1. If it is not already displayed, select your desired organization from the Organizations menu in the navigation bar.

  2. Click the Organization Settings icon next to the Organizations menu.

2

In Manage Federation Settings, click Open Federation Management App.

3
  1. Click Add a Domain.

  2. On the Domains screen, click Add Domain.

  3. Enter the following information for your domain mapping:

    Field
    Description
    Display Name
    Name to easily identify the domain.
    Domain Name
    Domain name to map.
  4. Click Next.

Note

You can choose the verification method once. It cannot be modified. To select a different verification method, delete and recreate the domain mapping.

Select the appropriate tab based on whether you are verifying your domain by uploading an HTML file or creating a DNS TXT record:

Upload an HTML file containing a verification key to verify that you own your domain.

  1. Click HTML File Upload.

  2. Click Next.

  3. Download the mongodb-site-verification.html file that Atlas provides.

  4. Upload the HTML file to a web site on your domain. You must be able to access the file at <https://host.domain>/mongodb-site-verification.html.

  5. Click Finish.

Create a DNS TXT record with your domain provider to verify that you own your domain. Each DNS record associates a specific Atlas organization with a specific domain.

  1. Click DNS Record.

  2. Click Next.

  3. Copy the provided TXT record. The TXT record has the following form:

    mongodb-site-verification=<32-character string>
  4. Log in to your domain name provider (such as GoDaddy.com or networksolutions.com).

  5. Add the TXT record that Atlas provides to your domain.

  6. Return to Atlas and click Finish.

The Domains screen displays both unverified and verified domains you've mapped to your IdP. To verify your domain, click the target domain's Verify button. Atlas shows whether the verification succeeded in a banner at the top of the screen.

After successfully verifying your domain, associate the domain with your IdP:

Important

Before you begin testing, copy and save the Bypass SAML Mode URL for your IdP. Use this URL to bypass federated authentication in the event that you are locked out of your Atlas organization.

While testing, keep your session logged in to the Federation Management Console to further ensure against lockouts.

To learn more about Bypass SAML Mode, see Bypass SAML Mode.

To test the integration between your domain and your IdP:

Example

If your verified domain is mongodb.com, enter alice@mongodb.com.

3

If you mapped your domain correctly, you're redirected to your IdP to authenticate. If authenticating with your IdP succeeds, you're redirected back to Atlas.

Note

You can bypass the Atlas log in page by navigating directly to your IdP's Login URL. The Login URL takes you directly to your IdP to authenticate.

You cannot delete a domain mapping if it is associated with an IdP. To disassociate a domain from an IdP:
