This Python package provides some helper functions to allow programmatic retrieval of temporary AWS credentials from STS_ (Security Token Service) when using federated login with `Shibboleth IDP`_.

The implementation relies on HTML parsing of the Shibboleth redirect page (HTML form) and the AWS role selection page.

This package requires Python 3.4.

Installation
============

.. code-block:: bash

    $ sudo pip3 install --upgrade aws-saml-login

Usage
=====

.. code-block:: python

    from aws_saml_login import authenticate, assume_role, write_aws_credentials, get_boto3_session

    # authenticate against identity provider
    saml_xml, roles = authenticate('https://shibboleth-idp.example.org', user, password)

    print(roles)

    # just use the first role here, we might display a user dialog to choose one
    first_role = roles[0]

    provider_arn, role_arn, account_name = first_role

    # get temporary AWS credentials
    key_id, secret, session_token = assume_role(saml_xml, provider_arn, role_arn)

    # write to ~/.aws/credentials
    write_aws_credentials('default', key_id, secret, session_token)

    # get boto3 session
    session = get_boto3_session(key_id, secret, session_token)
    ec2 = session.resource('ec2', 'eu-west-1')
    iam = session.client('iam')

    # get boto3 session with default region eu-central-1
    session = get_boto3_session(key_id, secret, session_token, 'eu-central-1')
    ec2 = session.resource('ec2')

    # get session for the first 5 roles
    sessions = {}
    for role in roles[:5]:
      provider_arn, role_arn, account_name = role
      key_id, secret, session_token, expiration = assume_role(saml_xml, provider_arn, role_arn)
      sessions['{} {}'.format(account_name,role_arn.split(':')[-1])] = get_boto3_session(None, key_id, secret, session_token)

    for key in sessions.keys():
      print('Key: {} / AccountAlias: {}'
            .format(key,
                    sessions[key].client('iam').list_account_aliases()['AccountAliases']))
    # AWS SDK (e.g. boto) can be used to call AWS endpoints
