OpenXPKI::Service::DefUser(Contributed Perl DocumOpenXPKI::Service::Default(3)

       OpenXPKI::Service::Default - basic service implementation

       This is the common Service implementation to be used by most
       interactive clients. It supports	PKI realm selection, user
       authentication and session handling.

Protocol Definition
   Connection startup
       You can send two	messages at the	beginning of a connection. You can ask
       to continue an old session or you start a new session. The answer is
       always the same - the session ID	or an error message.

       Session init

       --> {SERVICE_MSG	=> "NEW_SESSION",
	    LANGUAGE	=> $lang}

       <-- {SESSION_ID => $ID}


       <-- {SERVICE_MSG	=> "GET_PKI_REALM",
	    PARAMS => {
		PKI_REALM  => {
			    "0"	=> {
				    NAME => "Root Realm",
				    DESCRIPTION	=> "This is an example root

       --> {SERVICE_MSG	=> "GET_PKI_REALM",
	    PARAMS => {
		PKI_REALM => $realm,

	    PARAMS => {
			   "0" => {
				    NAME => "Basic Root	Auth Stack",
				    DESCRIPTION	=> "This is the	basic root
       authentication stack."

	    PARAMS => {
	   } Example 1:	Anonymous Login


       Answer is the first command.

       Example 2: Password Login

	    PARAMS => {
		       NAME	   => "XYZ",
		       DESCRIPTION => "bla bla ..."

       --> {LOGIN  => "John Doe",
	    PASSWD => "12345678"}

       on success ...  <-- {SERVICE_MSG	=> "SERVICE_READY"}

       on failure ...  <-- {ERROR => "some already translated message"}

       Session continue

	    SESSION_ID	=> $ID}

       <-- {SESSION_ID => $ID}



       The functions does nothing else than to support the test	stuff with a
       working user interface dummy.

       o   START

       o   init

	   Receives messages, checks them for validity in the given state and
	   passes them of to __handle_message if they are valid. Runs until it
	   reaches the state 'MAIN_LOOP', which	means that session
	   initialization, PKI realm selection and login are done.

       o   run

	   Receives messages, checks them for validity in the given state
	   (MAIN_LOOP) and passes them to __handle_message if they are valid.
	   Runs	until a	LOGOUT command is received.

       o   __is_valid_message

	   Checks whether a given message is a valid message in	the current
	   state. Currently, this checks the message name ('SERVICE_MSG')
	   only, could be used to validate the input as	well later.

       o   __handle_message

	   Handles a message by	passing	it off to a handler named using	the
	   service message name.

       o   __handle_NEW_SESSION

	   Handles the NEW_SESSION message by creating a new session, saving
	   it in the context and sending back the session ID. Changes the
	   state to 'SESSION_ID_ACCEPTED'

       o   __handle_CONTINUE_SESSION

	   Handles the CONTINUE_SESSION	message.

       o   __handle_PING

	   Handles the PING message by sending back an empty response.

       o   __handle_SESSION_ID_ACCEPTED

	   Handles the 'SESSION_ID_ACCEPTED' message. It looks whether there
	   are multiple	PKI realms defined. If so, it sends back the list and
	   changes to state 'WAITING_FOR_PKI_REALM'. If	not, it	looks whether
	   an authentication stack is present. If not, it sends	the list of
	   possible stacks and changes the state to

       o   __handle_GET_PKI_REALM

	   Handles the GET_PKI_REALM message by	checking whether the received
	   realm is valid and setting it in the	context	if so.

       o   __handle_GET_AUTHENTICATION_STACK

	   Handles the GET_AUTHENTICATION_STACK	message	by checking whether
	   the received	stack is valid and setting the corresponding attribute
	   if it is

       o   __handle_GET_PASSWD_LOGIN

	   Handles the GET_PASSWD_LOGIN	message	by passing on the credentials
	   to the Authentication modules 'login_step' method.

       o   __handle_DETACH

	   Removes the current session from this worker	but does not delete
	   the session.	The worker is now free to handle requests for other

       o   __handle_LOGOUT

	   Handles the LOGOUT message by deleting the session from the

       o   __handle_STATUS

	   Handles the STATUS message by sending back role and user

       o   __handle_COMMAND

	   Handles the COMMAND message by calling the corresponding command if
	   the user is authorized.

       o   __pki_realm_choice_available

	   Checks whether more than one	PKI realm is configured.

       o   __list_authentication_stacks

	   Returns a list of configured	authentication stacks.

       o   __is_valid_auth_stack

	   Checks whether a given stack	is a valid one.

       o   __is_valid_pki_realm

	   Checks whether a given realm	is a valid one.

       o   __change_state

	   Changes the internal	state.
