Wrong Signature Algorithm attribute in Authentication Request



When generating an authentication request in pySAMLWebSSOAuthenticationActivity, the system generates an incorrect SignatureMethod Algorthm.

That is,
<ds:SignatureMethod Algorithm=""/> is not generated.
<ds:SignatureMethod Algorithm=""/> is generated.

This occurs when using:
  • SAML based Single sign-on (SSO) for Smart Dispute Access using Web and Pega Web Mashup
  • Certificates with RSA - SHA256 encryption

Error Messages

Not Applicable

Steps to Reproduce

Log an SAML request in Pega in cloud or on Active Directory Federation Services (ADFS).

Root Cause

A defect in Pegasystems’ code or rules.

The signature algorithm was hard coded. The signature algorithm was fetched from the SP certificate.


Apply HFix-41903.
