I think that I have it really close, changed the email templates to reference hydrants and renamed the layer. Everything seems to be working independently, until I put it together in the Web Appbuilder (developer edition). At that point when I enter an email to signup/login I get a generic error "unable to complete operation". I think it must have something to do with the AuthGP service. An entry is never made in the usertable and an email is never sent. The AuthGP service does run in Arcmap before publishing the service. Any ideas would be appreciated.
