SAML Authenticator for Ping Federate

Acquire temporary CLI credentials via SAML federation.

Installation

$ pip3 install --trusted-host pypi.org --trusted-host files.pythonhosted.org -r requirements.txt
$ pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org -r requirements.txt

More info: Boto config tutorial

Update with Ping Federate URL and if MFA is needed there are several lines to adjust. 

If MITM proxy used, add the ca_bundle.crt to the folder and adjust the script.

Ping Federate will parse AD groups and create assertion for role switcher.  

The OGNL file can be adjusted accordingly to parse the groups for the assertion.  

The current format for the AD groups is 
AWS-SSO-<AWS ROLE>-<AWS ACCOUNT NUMBER> 
and will populate the assertion to provide the role switcher.
