# Module: Guest Authenticate
# Author: Matt Giuca
# Date: 21/2/2008
# Pluggable authentication module for LDAP servers.
# This module is part-test part-something-you-may-want.
# If enabled, it allows "external auth" against an account "guest" with
# password "guest".
# It may be called with a None user, and will return a guest User object,
# which will mean it gets put in the database.
# Thus it behaves similarly to a module which retrieves user details from an
# external source like LDAP.
# This module is NOT active implicitly - it must be specified in the
# "auth_modules" config string.
from ivle.auth import AuthError
from ivle.database import User
# XXX: What to put here

"""
A plugin auth function, as described above.
This one authenticates against a "guest"/"guest" account.
Returns user if successful. Raises AuthError if unsuccessful.
Returns a new User object if user is None.
