Unable to process the SAML WebSSO request

SA-97539

Summary



Single Sign-On (SSO)  login does not function correctly and an error occurs. The Authentication Service rule does not map embedded page values.


Error Messages



Unable to process the SAML WebSSO request : No value specified for Attribute in SAML assertion


Steps to Reproduce

  1. Use the D_SAMLAssertionDataPage.Subject.NameID.Value for the Attribute field.
  2. Log in to the application using SAML login with NameID as the userID.


Root Cause



A defect in Pegasystems’ code or rules. 
SSO login generated the error because the Authentication Service rule only maps attributes that are on the top level page and does not consider embedded page values.


Resolution



As a local-change, use tools.getProperty to fetch the property reference value instead of findPage and getString.

This feature is implemented in Pega Platform 8.3.2.
