Definitions
- [low] Placeholder values provided in the configuration are not intended for production use and must be replaced in a later step. Sources: https://www.mongodb.com/docs/atlas/security/federated-auth-okta.md [source]
How it works
- [low] The Organization Owner role should be heavily restricted and not assigned to a human because it can change organization-wide settings and delete configurations. Sources: https://www.mongodb.com/docs/atlas/architecture/current/auth/authorization.md [source]
Problems, failure modes and limitations
- [low] If the domain mapping is not created, SAML login will crash with an okta/hooks/acserror. Sources: https://www.mongodb.com/community/forums/t/mongodb-atlas-okta-integration-login-error/230897 [source]
Facts and statements
- [medium] While a federated IdP is enabled in Atlas, the platform disables any other authentication mechanisms. Sources: https://www.mongodb.com/docs/atlas/security/federated-authentication.md, https://www.mongodb.com/docs/atlas/security/manage-federated-auth.md [source]
- [low] Atlas routes users with email addresses using mapped domains to the associated Identity Provider (IdP). Sources: https://www.mongodb.com/docs/atlas/security/federated-authentication.md [source]
- [low] Attribute names in the SAML configuration are case-sensitive and must be typed in camelCase as shown in the documentation. Sources: https://www.mongodb.com/docs/atlas/security/manage-federated-auth.md [source]
- [low] Once an IdP is linked to Atlas, it appears as Inactive in the Federation Management Console until at least one domain is mapped to it. Sources: https://www.mongodb.com/docs/atlas/security/manage-federated-auth.md [source]
- [low] Using the federation resource requires an existing identity provider (IdP) linked to the Atlas organization. Sources: https://www.mongodb.com/docs/atlas/operator/current/atlasfederatedauth-custom-resource.md [source]
