=========================================================

This Python package is a high-level wrapper for Kerberos (GSSAPI) operations.
The goal is to avoid having to build a module that wraps the entire Kerberos.framework,
and instead offer a limited set of functions that do what is needed for client/server
Kerberos authentication based on <http://www.ietf.org/rfc/rfc4559.txt>.

Much of the C-code here is adapted from Apache's mod_auth_kerb-5.0rc7.

BUILD
=====

In this directory, run:

    python setup.py build

=======
TESTING
=======

You must have a valid Kerberos setup on the test machine and you should ensure that you have valid
Kerberos tickets for any client authentication being done (run 'klist' on the command line).
Additionally, for the server: it must have been configured as a valid Kerberos service with the Kerbersos server
for its realm - this usually requires running kadmin on the server machine to add the principal and generate a keytab
entry for it (run 'sudo klist -k' to see the currently available keytab entries).

Make sure that PYTHONPATH includes the appropriate build/lib.xxxx directory.
Then run test.py with suitable command line arguments:

    python test.py -u userid -p password -s service
    
    -u : user id for basic authenticate
    -p : password for basic authenticate
    -s : service principal for GSSAPI authentication (defaults to 'http@host.example.com')
