Django : intercept authentication to store session variable or cookie -

i working on project that's running on django. authenticate in multiple places. first, maintain standard authentication mechanism , continue using site administration. second, intercept login request in addition standard authentication, , check if user has authenticated on system , store session variable or cookie used later if authenticated. on logout remove session variable or cookie. second authentication mechanism should not affect first. in addition, if first succeeds , second fails, should have no affect on standard administration.

i have looked declaring custom authentication backend in settings authentication_backends tuple. understand, authenticates in order , stop authenticating once match made.

any guidance in regards appreciated.

if need set , unset cookie or session var can use signals sent authentication module (docs)

example:

from django.contrib.auth.signals import user_logged_in, user_logged_out  def user_logged_in_hook(sender, **kwargs):     # kwargs contain request , user objects     print kwargs   def user_logged_out_hook(sender, **kwargs):     # kwargs contain request , user objects     print kwargs   user_logged_in.connect(user_logged_in_hook) user_logged_out.connect(user_logged_out_hook)
