We are configuring SAML for authenticating into our application with Okta as IdP. More details on what we have done in Pega 7.2 -

a. SAML Auth service used, so no changes in prweb.xml file.

b. SAMLAuthIDPCertStore which was created automatically has been used at IdP setting and SP setting of auth service.

c. Attribute NameID has been mapped to pyUserIdentifier

d. Auth service is built on our version of Unauthenticated ruleset (which has been saved as from original Unauthenticated)

1* While accessing application through IdP , are are getting "Unable to process the SAML WebSSO request : 1"

The log shows - Error while executing the Assertion Consumer Service activity : 1

2* While accessing application through /prweb/sso link in browser, getting error -

Unable to process the SAML WebSSO request : Unable to process SAML2 Authentication response : No attribute statements found in the SAML Response,Unable to deduce an operator record for further processing

Have checked this article  but it did not help us.

Have anybody faced similar error? Please share to troubleshoot.
