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:
Start the editing session.
Edit the realm's user data.
Lists all of the users.
Add a new user.
Delete a user.
Add a new role to a user.
Delete a role from a user.
Lists all of the pending changes that have been made to the realms, but have not been applied to the container.
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.
jaas: then press Tab at the prompt to view the available commands.
