SFDC Pega Integration with SAML authentication throws error



Pega 7.1.9 with SFDC (Salesforce Process Extender) does not work. It throws authentication related error message in the browser.

Error Messages

Steps to Reproduce

Scenario 1 :
  1. User logs in to URL https://<host>:<port>/prweb/Servlet1 ( which is Pega 7.1.9 SAML 2.0 enabled – SAML authentication service )
  2. User prompted for user ID and password by SAML Identity provide
  3. User successfully logs in

Scenario 2

  1. User logs in to Salesforce ( not SAML enabled ) - https://<salesforce url>
  2. User initiates workflow within Pega using Salesforce Extender and makes request to same URL https://<pega host>:<port>/prweb/Servlet1 with additional query parameters
  3. Since this URL is linked to SAML enabled authentication service, it is expected that the user is prompted for credentials by SAML Identity provider, but instead an error message is displayed

Root Cause

An issue in the custom application code or rules. Closer look at the Pega Web Mashup configuration, revealed that  '<env name="/Authentication/RedirectGuests" value="false"/>' is missing.


Here’s the explanation for the reported behavior: 

Add below configuration setting by updating prconfig.xml or DSS (Dynamic System Setting) (refer to

<env name="/Authentication/RedirectGuests" value="false"/>
