routes

GET     /login/auth                 controllers.Application.auth()
GET     /login/verify		    controllers.Application.verify()

can someone briefly describe the details.It's showing error..what is Logger.debug("authenticate"); ,

Logger is play.Logger. Just add:

import Play.Logger;

to make it work.
