Configuring a Resource Server Adapter

A Resource Server Adapter (RSA) can be considered a middleware between the Authorization Server and Wallet within the FPX ecosystem and a Resource Server that is owned and operated by a third-party provider. As such, the configuration of the RSA is heavily dependent on the various protocols of the Resource Server. Given that there might be several Resource Servers within an ecosystem with each having its own protocols and authentication mechanisms, a 'one-size fits all' approach cannot be adopted when setting up an RSA.

The two most commonly used authentication protocols are OIDC (OpenID Connect) and LDAP (Lightweight Directory Access Protocol). Hence, to simplify and expedite deployments, IDENTOS provides the FPX solution package with configuration connectors and details for setting up an RSA with Resource Servers using either one of these two protocols.

Depending on the protocol selected, the configuration of the RSA Helm chart used during deployment will vary. The following sections will explain concepts and configuration details related to OIDC and LDAP in further detail.


These sections detail configuration requirements for the two most common protocol integrations at the RSA level. In addition to these two adapters, other RSAs can be set up, configured and customized to adapt to any other authentication protocol which might be used by the Resource Server. Please contact your IDENTOS Technical Representative for further details.
