Example SAML implementation using Python Requests

requests-saml.py

from requests.auth import AuthBase

class SAML(AuthBase):
    from bs4 import BeautifulSoup
    """Implemeents SSO with RH auth.redhat.com"""
    def __init__(self, username, password):
        # setup any auth-related data here
        self.username = username
        self.password = password

    def response_hook(self, response, **kwargs):
        if response.status_code == 401:
            '''RHSSO login page that says 'no kerberos ticket found. click form submit to to be redirected to text based login form'''
            soup = BeautifulSoup(response.text, 'html.parser')

            _r = response.connection.send(requests.Request('GET', soup.form['action'],
                cookies=response.cookies).prepare(), **kwargs)

            soup2 = BeautifulSoup(_r.text, 'html.parser')

Example:
import requests
### from directory import class(SAML)
import getpass

s = requests.Session()
s.auth = SAML(raw_input("username: "), getpass.getpass("password: "))
r = s.get('https://example.domain.com')
