The recommended file name is zookeeper-jaas.conf. When using a ZooKeeper cluster with multiple nodes, the JAAS configuration file has to be created on all cluster nodes. JAAS is configured using contexts. Separate parts such as the server and client are always configured with a separate context. You need to set the JAAS configuration file path as JVM parameter for client and broker. For example:-Djava.security.auth.login.config=/etc/pulsar/pulsar_jaas.conf In the pulsar_jaas.conf file above. PulsarBroker is a section name in the JAAS file that each broker uses. This section tells the broker to use which principal inside Kerberos and the location of the keytab where the principal is stored.
Jun 28, 2018 · For the jaas.conf file used for ZooKeeper authentication and the keytab file and principal file used for Kerberos authentication, you can contact the administrator to create the files and obtain them. For details about how to use the files, see related description in the example code.

Hi Kevin, I'm glad you made JOSSO work. You are right, it shouldn't be needed for the user to logon again. We tested it and its a bug which occurs when the user does a signon directly without requesting a protected resource.
To run the client application using JAAS-based authentication and authorization, it is necessary to include the CLASSPATH containing the LoginModule and to specify the login module configuration file and JAAS principal-based policy file as command-line options or as system properties (see Example 4-45).
For example, saving test-plan.jmx will create a test-plan-000012.jmx in the backup directory provided that the last created backup file is test-plan-000011.jmx. Default value is true indicating that auto backups are enabled.
The following example application starts with the example provided in Developing with NetBeans and demonstrates adding security to both the web service and to the web service client. For this example, the security mechanism of SAML Sender Vouches with Certificates is used to secure the application.
Later on when, client request comes in, client’s Kerberos token will be validated against this security context. Note the usage of GSSContext class, which is part of GSS API, to authenticate the client’s Kerberos token and encrypt (wrap method) and decrypt (unwrap method) the messages between client and server.
Note: Ensure that installing client for the connectors, copying of JAR's file and configuration changes tasks are performed on all the nodes of the cluster. Locate the [appserverdomain]/ config/config.xml file and make a backup copy of it.
