MockCAS - Mock CAS Server for Testing

This is a simple little CAS server that was born out of a need for a highly configurable CAS server to support load testing. Emphasis is on simplicity, flexibility, and performance. The following SSO protocols are supported:

  1. CAS 1.0
  2. CAS 2.0
  3. SAML 1.1

The server implements a stupid simple routine for serving protocol responses from files on disk under $DATA_DIR:

for authenticated user $USER on supported protocol $PROTOCOL, serve the file $DATA_DIR/$PROTOCOL/$USER. It is the responsibility of deployers to generate appropriate protocol data in the files, which provides maximum flexibility for setting up test data sets at the expense of some up-front effort generating the test data.

The sampledata directory demonstrates the required layout of the $DATA_DIR directory. The files therein may be used as starting points for creating a test data set for your needs. It's only necessary to create files under the protocols you intend to support for testing.

Limitations

The design goal of simplicity, both in implementation and configuration, incurs some notable limitations.

  1. No support for TLS
  2. Password authentication exclusively with single, static password
  3. No proxy support
  4. No single logout support

Requirements

The only software requirement is Python 3.2 or later. It's recommend to run the server on a secure private network due to the lack of TLS support.

Usage

usage: server.py [-h] [--address ADDRESS] [--port PORT] secret data_dir

Start the mock CAS server

positional arguments:
  secret             static secret used to authenticate users
  data_dir           path to data directory

optional arguments:
  -h, --help         show this help message and exit
  --address ADDRESS  server bind address, 0.0.0.0 by default
  --port PORT        server listen port, 8080 by default
