Question I am having issues connecting to my Microsoft Active Directory using the devise_ldap_authentication. For some reason I keep getting LDAP search yielded 0 matches when using it with devise and I am 100% certain I am using the correct credentials, so I wrote a test class using 'net/ldap' to see if I could yeild a correct match and presto it works with my test class but, I still can't authenticate with devise_ldap_auth. Any help would be greatly appreciated or help with setting up my config/ldap.yml to match my test class.

Here is my config/ldap.yml

#Environment
development:
  host: myldap.mydomain.com
  port: 389
  attribute: sAMAccountname
  base: dc=mydomain, dc=com
  admin_user: cn=admin,dc=mydomain,dc=com
  admin_password: password
  #ssl: false

Here is my devise.rb

Devise.setup do |config|
  # ==> LDAP Configuration
  config.ldap_logger = true
  # config.ldap_create_user = false
  # config.ldap_update_password = true
  config.ldap_config = "#{Rails.root}/config/ldap.yml"
  # config.ldap_check_group_membership = false
  # config.ldap_check_group_membership_without_admin = false
  config.ldap_check_attributes = true
  #config.ldap_use_admin_to_bind = true
  # config.ldap_ad_group_check = false

this is what I get back when using ldap with devise.

Here is my test class that works to authenticate with ldap on my microsoft AD

require 'net/ldap' # gem install ruby-net-ldap
module Test
  class PutAd
    SERVER = 'myldap.mydomain.com'
    PORT = 389
    BASE = 'DC=mydomain,DC=com'
    DOMAIN = 'mydomain.com'

    ATTR_SV = {
                :login => :samaccountname,
                :first_name => :givenname,
                :last_name => :sn,
                :email => :mail
              }


    def self.authenticate(login, pass)
      return nil if login.empty? or pass.empty?

      conn = Net::LDAP.new :host => SERVER,
                           :port => PORT,
                           :base => BASE,
                           :auth => { :username => "#{login}@#{DOMAIN}",
                                      :password => pass,
                                      :method => :simple }
      if conn.bind and user = conn.search(:filter => "sAMAccountName=#{login}").first
        return self.new(user)
      else
        return nil
      end
    rescue Net::LDAP::LdapError => e
      return nil
    end
  end 
end 

^This will return my account information if it matches if not it will return nil.
