To Add custom conditions to authlogic finders first of all we need to override authlogic find_by_login method.

class UserSession < Authlogic::Session::Base
  after_validation :check_if_verified
  find_by_login_method :find_by_login_and_deleted_method
end

Then we need to define overridden method inside User model

class User < ActiveRecord::Base
  acts_as_authentic
  def self.find_by_login_and_deleted_method(login)
    find_by_email_and_deleted(login, false)
  end
end

got easy..wooooooo :)
