Fixed version of SecureModule

SecureModule.scala

import scaldi.{Injector, Module, Injectable}

trait Security {
  type User

  def authenticate(username: String, password: String): Boolean
}

class SecuritySample extends Security {
  def authenticate(username: String, password: String): Boolean = false
}

class SecurityImpl extends Security {

  def authenticate(username: String, password: String): Boolean = {
    User.authenticate(username, password) match {
      case Some(user: User) => true
      case _ => false
    }
  }
}

class ModSec(implicit inj: Injector) extends Injectable {
  def secure = inject [Security] (identified by 'secure and by default new SecuritySample)
}

object ConfigModule extends Module {
  bind [Security] as 'secure to new SecurityImpl
  bind [ModSec] to new ModSec
}
