变量Errno :: ETIMEDOUT在设计:: SessionsController＃创建ETIMEDOUT与设计（导轨）LDAP验证
我试图创建一个使用Devise与LDAP Authentication Rails应用程序。
不幸的是，我不认为我的LDAP设置是正确的，但我不知道如何打印出超时发生的更详细的错误信息。
这里是我的LDAP配置：
development:
host: ad.cloud.domain.com
#port: 389
#attribute: cn
base: DC=cloud,DC=domain,DC=com
#admin_user: dc=cloud,dc=domain,dc=com
#admin_password:
ssl: false
# <<: *AUTHORIZATIONS
我知道，我们没有使用SSL，因为我已经从一个类似的PHP应用程序移植这个配置了，但PHP应用程序没有属性字段。也许这是我不明白的？
我发现了一个fewquestions引用如何更改错误以及它如何与网络连接，但我无法找到我的资源了解Net :: LDAP库，以及此连接失败，什么我错过了，我不明白。我已验证网络连接，并使用Windows客户端通过匿名访问验证了LDAP权限。
这里的输出，跟踪和转储：
Errno::ETIMEDOUT in Devise::SessionsController#create
Connection timed out - connect(2)
