Hi,

We have configured a SAML 2.0 authentication service rule in Pega 7.4. This is an idp initiated transaction. When trying to connect, we are seeing a wired error in the logs.

Custom authentication service invalid, an Authentication Activity is required in the Data-Admin-AuthService instance

We have provided the authentication activity. Activity provided is pySAMLWEBSSOAuthenticationActivity in code-security. The RS is available in the application that maps to un authenticated accessgroup. Can some one help please? Thanks
