ruby-on-rails – 设计无视自定义策略

这很奇怪.

我有Rails 3 RC运行与Devise安装.我已经定义了一个自定义策略来尝试使用Kerberos进行身份验证.

@H_697_4@module Devise module Strategies class Kerb < Devise::Strategies::Base def valid? params[:username] || params[:password] end def authenticate! # cheap debugging puts "PARAMS: #{params}" if check_kerb_auth(params[:username],params[:password]) # create user account if none exists u = User.find(:first,:conditions => { :username => params[:username] }) || User.create({ :username => login }) success!(u) else fail!("Could not log in") end end def check_kerb_auth(username,password) require 'krb5_auth' include Krb5Auth return false if username.blank? or password.blank? begin kerberos = Krb5.new return kerberos.get_init_creds_password(username,password) rescue Krb5Auth::Krb5::Exception return false end end end end end

我的Devise Warden配置设置如下：

config.WARDen do |manager|
  manager.strategies.add(:kerb,Devise::Strategies::Kerb)
  manager.default_strategies :kerb
end

我的日志中没有错误.一切似乎都行了.如果我添加了“廉价调试”一堆put语句,似乎反映出：路由策略是默认的.以下是登录尝试的一组日志记录：

kerberos代码在同一台机器上的其他工作.我有一种期待它出现一堆错误,如果有一个问题,但我什么也没有.有没有好的方法来调试Devise / WARDen？

def valid?
  params[:username] || params[:password]
end

def valid?
  params[:user] && (params[:user][:username] || params[:user][:password])
end
