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
- Use the D_SAMLAssertionDataPage.Subject.NameID.Value for the Attribute field.
- 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.
