The jaas commands are used for editing JAAS realm and user data. Editing a JAAS realm is done in two stages. The changes are placed in a queue until they are applied by executing the jaas:update.
When editing JAAS settings the commands are used as follows:
  1. Start the editing session.
  2. Edit the realm's user data.
    • jaas:users
      Lists all of the users.
    • jaas:useradd
      Add a new user.
    • jaas:userdel
      Delete a user.
    • jaas:roleadd
      Add a new role to a user.
    • jaas:roledel
      Delete a role from a user.
    • jaas:pending
      Lists all of the pending changes that have been made to the realms, but have not been applied to the container.
  3. Apply the changes to the JAAS realm and ends the editing session.
You can abandon an editing session using jaas:cancel before the changes applied to the JAAS settings.
Type jaas: then press Tab at the prompt to view the available commands.

jaas:cancel [ --help ]


When editing a JAAS realm, the changes are buffered until the editing session is closed. The jaas:cancel command clears the buffer without saving the changes and closes the editing session.
You can see a list of the buffered changes using the jaas:pending command.
