我的 Omniauth 初始化程序:

My Omniauth Initilaizer:

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :LDAP, "Ed-ITLDAP", :host => LDAP_HOST, :port => LDAP_PORT, :method => 'plain', :base => LDAP_BASE, :uid =>  'sAMAccountName', :try_sasl => true, :sasl_mechanisms => "GSS-SPNEGO"
end

<小时>

Omniauth 似乎不再需要/需要提供者的名称，因此在我的情况下，我从提供者行中删除了EDITLDAP"选项，如下所示:

---

Omniauth seems to longer want/need the name of the provider so in my case I removed the "EDITLDAP" option from the provider line like this:

Rails.application.config.middleware.use OmniAuth::Builder do
    provider :LDAP, :host => LDAP_HOST, :port => LDAP_PORT, :method => 'plain', :base => LDAP_BASE, :uid =>  'sAMAccountName', :try_sasl => true, :sasl_mechanisms => "GSS-SPNEGO"
end

推荐答案

@Arcath:检查您使用的任何中间件是否使用正确的语法.我遇到了同样的问题，问题是我的 config.ru 有

@Arcath: check that any middleware you're using is using the right syntax. I had the same problem and the issue was that my config.ru had

use Rails::Rack::Static

现在在 Rails 3 中:

which in Rails 3 is now:

use Rack::Static
