[Code] AX Security in python-openid

[Mike Sun]

Hi -- 

I'm using python-openid for my RP and Google Marketplace wanted to make sure this implementation is not vulnerable to spoofed, non-signed attributes such as email addresses.

See: http://googlecode.blogspot.com/2011/05/security-advisory-to-websites-using.html

Looking at the python-openid code, it seems that the default requires that only signed attributes are allowed to passed in the response.

See: https://github.com/openid/python-openid/blob/master/openid/extensions/ax.py

Can anyone confirm that it is true that python-openid checks that the attribute is signed by the correct corresponding IDP?

Thanks,
Mike
