I am writing a user story and have a simple questions.Consider, I am writing it for login module which calls internally a web service to authenticate the user and returns the data. How this can be converted into a  user story.Should this be written as:As a user,I would like to login to the system and see the resultset.and leave it or should I write validations/web service call as well as well.As I understand, as a user I am not concerned with web service. So how should I write about this?
