This example presents a pure Java client, C, that accesses a secure
enterprise bean on server, S1, through user bob. The following steps take
you through the configuration of C, S1, and S2.
The
enterprise bean code on S1 accesses another enterprise bean on server, S2.
This configuration uses identity assertion to propagate the identity of bob
to the downstream server, S2. S2 trusts that bob already is authenticated
by S1 because it trusts S1. To gain this trust, the identity of S1 also flows
to S2 simultaneously and S2 validates the identity by checking the trustedPrincipalList
list to verify that it is a valid server principal. S2 also authenticates
S1. The following steps take you through the configuration of C, S1, and S2.
Configuring client, C
Client C requires message
layer authentication with a Secure Sockets Layer (SSL) transport. To accomplish
this task:
- Point the client to the sas.client.props file.
Use the com.ibm.CORBA.ConfigURL=file:/C:/was/properties/sas.client.props property.
All further configuration involves setting properties within this file.
- Enable SSL.
In this case, SSL is supported but not required: com.ibm.CSI.performTransportAssocSSLTLSSupported=true,
com.ibm.CSI.performTransportAssocSSLTLSRequired=false
- Enable client authentication at the message layer.
In this case, client
authentication is supported but not required: com.ibm.CSI.performClientAuthenticationRequired=false,
com.ibm.CSI.performClientAuthenticationSupported=true
- Use all of the remaining defaults in the sas.client.props file.
Configuring server, S1
In the administrative console,
server S1 is configured for incoming requests to support message-layer client
authentication and incoming connections to support SSL without client certificate
authentication. Server S1 is configured for outgoing requests to support identity
assertion.
- Configure S1 for incoming connections.
- Disable identity assertion.
- Enable user ID and password authentication.
- Enable SSL.
- Disable SSL client certificate authentication.
- Configure S1 for outgoing connections.
- Enable identity assertion.
- Disable user ID and password authentication.
- Enable SSL.
- Disable SSL client certificate authentication.
Configuring server, S2
In the administrative console,
server S2 is configured for incoming requests to support identity assertion
and to accept SSL connections. Complete the following steps to configure incoming
connections. Configuration for outgoing requests and connections are not relevant
for this scenario.
- Enable identity assertion.
- Disable user ID and password authentication.
- Enable SSL.
- Disable SSL client authentication.
