Scenario 2: Basic authentication, identity assertion and client certificates

This scenario is the same as Scenario 1, except for the interaction from client C2 to server S2. Therefore, the configuration of Scenario 1 still is valid, but you have to modify server S2 slightly and add a configuration for client C2. The configuration is not modified for C1 or S1.

 

Configuring client C2

Client C2 requires transport layer authentication SSL client certificates). To configure transport layer authentication:

1. Point the client to the sas.client.props file using the com.ibm.CORBA.ConfigURL=file:/C:/was/properties/sas.client.props property.

   All further configuration involves setting properties within this file.

2. Enable SSL.

   In this case, SSL is supported but not required:

   com.ibm.CSI.performTransportAssocSSLTLSSupported=true,
   com.ibm.CSI.performTransportAssocSSLTLSRequired=false
   

3. Disable client authentication at the message layer.

   com.ibm.CSI.performClientAuthenticationRequired=false, 
   com.ibm.CSI.performClientAuthenticationSupported=false
   

4. Enable client authentication at the transport layer where it is supported, but not required:

   com.ibm.CSI.performTLClientAuthenticationRequired=false, 
   com.ibm.CSI.performTLClientAuthenticationSupported=true 
   

 

Configuring server, S2

In the administrative console, server S2 is configured for incoming requests to SSL client authentication and identity assertion. Configuration for outgoing requests is not relevant for this scenario.

1. Enable identity assertion.

2. Disable user ID and password authentication.

3. Enable SSL.

4. Enable SSL client authentication.

You can mix and match these configuration options. However, there is a precedence to which authentication features become the identity in the received credential...

1. Identity assertion

2. Message layer client authentication (basic authentication or token)

3. Transport layer client authentication SSL(certificates)
