A company plans to add a modern authentication service. The team must connect the service to an older directory used by a partner, without major rewrites. Which method best promotes synergy among these environments?
Replace existing directories with the new platform
Replicate accounts by synchronizing records
Develop a data encryption process tailored to the new service
Set up a gateway that translates credentials for both environments
A bridging gateway (e.g., SAML-to-OIDC or LDAP-to-OAuth) translates authentication tokens or credentials between legacy directories and modern services. This avoids the need for intrusive rewrites or account duplication and ensures seamless interoperability between different authentication systems, preserving backward compatibility and reducing integration complexity.
