To use mutual authentication, servers and agents must exchange
keys. You export a server key as a certificate and import it into
the agent keystore, then reverse the process by exporting the agent
key and importing it into the server keystore.
Before you begin
Before you exchange keys, ensure that the following properties
are set:
- The server.jms.mutualAuth property in the
server's installed.properties file (in the server_install/conf/server directory)
is set to true.
- For each agent, the locked/agent.mutual_auth property
in the agent's installed.properties file (in
the agent_install\conf\agent directory)
is set to true.
- For each agent relay, the agentrelay.jms_proxy.secure property
in the relay's agentrelay.properties file (in
the relay_install\conf directory)
is set to true.
- For each agent relay, the agentrelay.jms_proxy.mutualAuth property
in the relay's agentrelay.properties file is
set to true.
Procedure
- Open a command-line window and go to the server installation conf directory.
- Run the following command:
keytool -export -keystore server.keystore -storepass changeit
-alias server -file server.crt
- Copy the exported file (certificate) to the agent installation conf directory
or the agent relay installation conf/jms-relay directory.
- Import the file by running the following command from within
the agent's conf directory or the agent relay's jms-relay directory:
keytool -import -keystore keystoreFile -storepass changeit
-alias server -file server.crt -keypass changeit -noprompt
For keystoreFile,
use ibm-ucd.keystore for agents and agentrelay.keystore for
agent relays. You should see the Certificate
was added to keystore message.
- For each local agent or agent relay, export the key by
running the following (change the name of the file argument to match
the agent name):
keytool -export -keystore keystoreFile -storepass changeit
-alias ibm-ucd_agent -file agentName.crt
For keystoreFile,
use ibm-ucd.keystore for agents and agentrelay.keystore for
agent relays. For agentName,
specify a unique string identifier for the agent or agent relay. You should see the message Certificate stored
in file agentName.crt.
- Copy the exported file to the server's conf directory.
- From within the server's conf directory,
import each certificate by running the following command:
keytool -import -keystore server.keystore -storepass changeit
-alias [agent_name] -file agentName.crt -keypass changeit -noprompt
You should see the Certificate was added to keystore message.
- Restart the server, agents, and agent relays.
What to do next
To connect an agent relay with the remote agents, swap
certificates as explained above: each remote agent must import the
certificate for the relay, and the relay must import the certificate
from each remote agent. Agents that use relays do not have to swap
certificates with the server.
To list the certificates that
are loaded into a keystore, run the following from within the keystore
directory:
keytool -list -keystore keystoreFile -storepass changeit
