There are two main perspectives on authentication:

1) A client application that needs access to a service in order to facilitate its actions. For these, see:
/c/alpha/communicate/communicate/authentication/README.txt

2) A server based service that needs to authenticate many local users of the service. For these, see:
/c/templates/django/authentication.txt


detailed documentation on this process are being written in communicate/communicate/authentication/README.txt
please see there for details.
