What?

This is a copy of Jon Rifkin’s Python CAS client. The original can be found at https://wiki.jasig.org/display/CASC/Pycas. This fork lives at https://github.com/ryanfox/pycas and on Pypi.

The original appears to have not been updated for some time now, and is not on Pypi. This is an attempt to rectify that situation.

Potential things to be added:

• Unit tests

• Better security:

  • Remove default secret key

  • Better yet, ditch md5 entirely

  • Add signed cookies (e.g. itsdangerous)

• Enforce the timeout

Installation

pip install pycas

Why?

The pycas CAS client provides CAS authentication for your Python CGI web application.

How?

STEPS TO ADD CAS AUTHENTICATION

1. Add four lines to your Python Web app like this:

   import pycas
   CAS_SERVER  = "https://casserver.mydomain"
   SERVICE_URL = "http://webserver.mydomain/cgi-bin/webapp.py"
   status, userid, cookie = pycas.login(CAS_SERVER, SERVICE_URL)

2. Process the returned variables:

   status carries the success or failure status.
   userid is the user's account name.
   cookie is the header string to send to the client if it's not empty.

For more information, see comments in the Python code.
