krbauth.py

Python wrapper module around kinit for simple Kerberos authentication.

Pre-requisites

You must have your machine configured as a Kerberos user. For debian based machines such as Ubuntu, this would involve installing the krb5-user package, and configuring the krb5.conf file.

Usage

It can be run as a script from the command-line. The usage help is shown below.

sumit@HAL9000:~/krbauth.py$ python3 krbauth.py -h
usage: krbauth.py [-h] [-u USERNAME] [-p PASSWORD] [-r REALM] [-q]

optional arguments:
  -h, --help            show this help message and exit
  -u USERNAME, --username USERNAME
                        Kerberos username
  -p PASSWORD, --password PASSWORD
                        Kerberos password
  -r REALM, --realm REALM
                        Kerberos REALM
  -q, --quiet           Quiet mode

You can also import and use the krbauth function directly in your Python program like the following. It returns a boolean value, signifying whether the login was successful or not.

>>> import krbauth
>>> krbauth.krbauth('username', 'password')
True
