My favorite way to debug SAML authentication is by using the SAML Chrome Panel plugin. Usually you'll find something stands out as being missing in the posted XML.
If you can paste the full stack trace that would be helpful.

Thanks Allen ,
I have attached the SAML Json coming out of Chrome Panel plugin. Most of the data Looks normal but at
"Name": "P3P"
"value": "CP=\"ADFS doesn't have P3P policy, please contact your site's admin for more details.\""
Any observations here is really helpful.

In continuation to above post -
While doing a remote trace of PYSAMLWEBSSOAUTHENTICATIONACTIVITY (Pega-IntegrationEngine:07-10-31), it is noticed that the Parameter page before executing step-1 has blank values. (pyQueryMap , pyPostDataMap, pyQuerystring etc.) because of which the activity Exits before creating datapages , Operator mapping etc.
Attached the sequence of steps executed.

The response in your attachment is encrypted. You can try decrypting it here: https://www.samltool.com/decrypt.php
Consider having your identity provide disable encryption until you can logon. Then add the encryption back in.
Post the stack trace from the PegaRULES log
