Topic: from Rails app to Salesforce - SAML Assertion Based Authentication
I have searched enough and then some more... and still no avail so posting this question here:
I wish to authenticate using SAML Bearer Assertion to access REST/Chatter APIs from Salesforce.
This involved generating valid SAML assertions and digitally signing it as per the the standard.
Without going into too much gory details, I am looking for something similar as available in Java (eg: OpenSAML) without having to do all the ground work myself (like canonical form or other low level stuff)
Hope someone knows a library/gem (paid or free) for this.
