           # example
           <Plugin::Authentication>
               <nopassword>
                   <credential>
                       class = NoPassword
                   </credential>
                   <store>
                       class = DBIx::Class
                       user_model = DB::User
                       role_relation = roles
                       role_field = name

           </Plugin::Authentication>

       This authentication credential checker takes authentication information (most often a username) and
       retrieves the user from the store. No validation of any credentials is done. This is intended for
       administrative backdoors, SAML logins and so on when you have identified the new user by other means.
