SAML login for AWS using Shibboleth IDP

Project description

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.


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


from aws_saml_login import authenticate, assume_role, write_aws_credentials

# authenticate against identity provider
saml_xml, roles = authenticate('', user, password)


# 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)

# AWS SDK (e.g. boto) can be used to call AWS endpoints
