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.
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.
Click Add a Domain.
On the Domains screen, click Add Domain.
Enter the following information for your domain mapping:FieldDescriptionDisplay NameName to easily identify the domain.Domain NameDomain name to map.
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:
After successfully verifying your domain, associate the domain with your IdP:
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:
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.
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:
- From the management console, click Identity Providers
- in the left navigation.
- For the IdP you want to disassociate from your domain, click
- Edit next to Associated Domains.
Deselect the domain desired domain.
To delete a domain from the Federation Management instance:
Click Add a Domain.
Open the Actions menu for the domain you want to delete.
