Configuring the outbound CSIv2 transport layer in the Liberty application client container
You can configure the Liberty application client container to perform client certificate authentication for outbound CSIv2 requests.
About this task
The client certificate authentication of the outbound CSIv2 transport layer for a Liberty application client container is not used by default. You can configure the transportLayer to specify the SSL configuration to use.
You can configure the SSL element to support client certificate authentication or require it. The certificate sent to the server is authenticated against the server user registry and its identity is only used if no other form of authentication is sent in the CSIv2 request, like an identity assertion in the attribute layer or an authentication token in the authentication layer.
