Unable to process the SAML WebSSO request



Unable to log in to the application using the newly configured SAML Authentication service and SAML WebSSO error message displays.

Error Messages

Error message: Unable to process the SAML WebSSO request

[tp-apr-8080-exec-298] [STANDARD] [ ] [ABC:01.01.01] (nActivity.Code_Security.Action) ERROR <host> - Error while executing the Authentication Service activity : No value specified for attribute mapped to pyUserIdentifier property

Steps to Reproduce

  1. Import the Identity Provider (IdP) metadata to configure an SAML Authentication Service rule.
  2. Configure the IdP.
  3. Log in to the application using the Single Sign-On (SSO) URL.

Root Cause

A third-party product issue.
The IdP did not return the Attribute Name (NameID) in the SAML response's AttributeStatement section. However, in the SAML Authentication Service rule, the user mapped the NameID attribute that was received with the pyUserIdentifier.


As a local-change, configure the IdP to return the NameID attribute in the SAML response's AttributeStatement section.
