How AuthenticationLDAP activities work in rendering the HTML for user credentials
I'm trying to understand how these OOTB activities (AuthenticationLDAP & LDAPAuthenticatio n & AuthenticationLDAPWebVerifyCredentials) work in rendering login page for user credentials. In all these activities, I see pyChallenge parameter is populating from PRAuthentication class like PRAuthentication.DEFAULT_CHALLENGE. As per engine API, these properties have default values & in this case @java("PRAuthentication.DEFAULT_CHALLENGE") results to <<DEFAULT_CHALLENGE>>. Based on this value, how Pega is rendering UI for entering user credentials. I see no stream rules defined in the Custom tab of the Authentication Service rule.
