Configuring an environment to use login modules with java clients

The login modules for use by clients are defined in the file $JONAS_ROOT/conf/jaas.config. Example:

jaasclient {
    // Login Module to use for the example jaasclient.

    //First, use a LoginModule for the authentication
    // Use the resource memrlm_1
    org.objectweb.jonas.security.auth.spi.JResourceLoginModule required
    resourceName="memrlm_1"
        ;

    // Use the login module to propagate security to the JOnAS server
    // globalCtx is set to true in order to set the security context
    // for all the threads of the client container instead of only
    // on the current thread.
    // Useful with multithread applications (like Swing Clients)
    org.objectweb.jonas.security.auth.spi.ClientLoginModule  required
    globalCtx="true"
        ;
};
    

This file is used when a java client is launched with jclient, as a result of the following property being set by jclient: -Djava.security.auth.login.config==$JONAS_ROOT/conf/jaas.config

For more information about the JAAS authentication, refer to the JAAS authentication tutorial.
