/**
	@brief Implement the "complete" method.
	@param ctx The method context.
	@return -1 upon error; zero if successful, and if a STATUS message has been sent to the
	client to indicate completion; a positive integer if successful but no such STATUS
	message has been sent.

	Method parameters:
	- a hash with some combination of the following elements:
		- "username"
		- "barcode"
		- "password" (hashed with the cached seed; not plaintext)
		- "type"
		- "org"
		- "workstation"

	The password is required.  Either a username or a barcode must also be present.

	Return to client: Intermediate authentication seed.

	Validate the password, using the username if available, or the barcode if not.  The
	user must be active, and not barred from logging on.  The barcode, if used for
	authentication, must be active as well.  The workstation, if specified, must be valid.

	Upon deciding whether to allow the logon, return a corresponding event to the client.
