Hi,

We are implementing SSO using SAML.  We have a requirement to allow a user to access Pega application when

1)SSO validation successful and

2)That user(operator) already exists in Pega application. 

But, if user is not existing, then we do not want to create a user in pega.  To achieve this, we not checked the checkbox "Enable operator provisioning using model operator" on Auth Service rule.  Currently, we are getting SAML standard error message.

But we want to show a customized message to user, so we are using post auth activity (pySSOPostAuthenticationActivity) and using field value to show custom message.   In this message, we also need to show a link, on which user can click to register.  I tried below but did not work.
