When logging in to Appian, via a SAML authentication system, the following error can be printed in the application server log:
[ajp-nio-0.0.0.0-8009-exec-3] ERROR com.appiancorp.security.auth.saml.redirecter.SamlAuthProviderQueryStringGenerator - Could not find IdP entity Id: Idp Entity Id not stored on session or request
This error indicates that a SAML user failed to authenticate. There are numerous causes that can print an error like that. Some of the issues can be related to the SAML setup or it may just be an incorrect credential attempt from an user.

This article applies to all versions of Appian.
