I’m getting the following issue when I try to authenticate at the sessions/new method:

 

Started POST "/users/sign_in" for 10.127.52.109 at 2012-12-11 11:42:22 -0600

Processing by Devise::SessionsController#create as HTML

  LDAP: LDAP dn lookup: cn=sg0218049

  LDAP: LDAP search for login: cn=sg0218049

Completed 401 Unauthorized in 849ms

 

My ldap.yml file is this:

 

## Authorizations

# Uncomment out the merging for each enviornment that you'd like to include.

# You can also just copy and paste the tree (do not include the "authorizations") to each

# enviornment if you need something different per enviornment.

authorizations: &AUTHORIZATIONS

#  group_base: ou=groups,dc=hostname-test,dc=com

  ## Requires config.ldap_check_group_membership in devise.rb be true

  # Can have multiple values, must match all to be authorized

#  required_groups:

    # If only a group name is given, membership will be checked against "uniqueMember"

    # - cn=admins,ou=groups,dc=test,dc=com

    # - cn=users,ou=groups,dc=test,dc=com

    # If an array is given, the first element will be the attribute to check against, the second the group name

    # - ["moreMembers", "cn=users,ou=groups,dc=test,dc=com"]

  ## Requires config.ldap_check_attributes in devise.rb to be true

  ## Can have multiple attributes and values, must match all to be authorized

  # <<: *AUTHORIZATIONS

 

And my config/initializers/devise.rb file looks like this:

 

# Use this hook to configure devise mailer, warden hooks and so forth.

# Many of these configuration options can be set straight in your model.

Devise.setup do |config|

  # ==> LDAP Configuration

  config.ldap_logger = true

  config.ldap_create_user = true

  # config.ldap_update_password = true

  config.ldap_config = "#{Rails.root}/config/ldap.yml"

  config.ldap_check_group_membership = false

  config.ldap_check_attributes = false

  config.ldap_use_admin_to_bind = true

  # config.ldap_ad_group_check = false

 

  # ==> Mailer Configuration

  # Configure the e-mail address which will be shown in Devise::Mailer,

  # note that it will be overwritten if you use your own mailer class with default "from" parameter.

  config.mailer_sender = "stratus@#{HOSTNAME}"

 

  # Configure the class responsible to send e-mails.

  # config.mailer = "Devise::Mailer"

 

  # ==> ORM configuration

  # Load and configure the ORM. Supports :active_record (default) and

  # :mongoid (bson_ext recommended) by default. Other ORMs may be

  # available as additional gems.

  require 'devise/orm/active_record'

 

  # ==> Configuration for any authentication mechanism

  # Configure which keys are used when authenticating a user. The default is

  # just :email. You can configure it to use [:username, :subdomain], so for

  # authenticating a user, both parameters are required. Remember that those

  # parameters are used only when authenticating and not when retrieving from

  # session. If you need permissions, you should implement that in a before filter.

  # You can also supply a hash where the value is a boolean determining whether

  # or not authentication should be aborted when the value is not present.

  # config.authentication_keys = [ :email ]

  config.authentication_keys = [ :username ]

 

  # Configure parameters from the request object used for authentication. Each entry

  # given should be a request method and it will automatically be passed to the

 # find_for_authentication method and considered in your model lookup. For instance,

  # if you set :request_keys to [:subdomain], :subdomain will be used on authentication.

  # The same considerations mentioned for authentication_keys also apply to request_keys.

  # config.request_keys = []

 

  # Configure which authentication keys should be case-insensitive.

  # These keys will be downcased upon creating or modifying a user and when used

  # to authenticate or find a user. Default is :email.

  config.case_insensitive_keys = [ :email ]

 

  # Configure which authentication keys should have whitespace stripped.

  # These keys will have whitespace before and after removed upon creating or

  # modifying a user and when used to authenticate or find a user. Default is :email.

  config.strip_whitespace_keys = [ :email ]

 

  # Tell if authentication through request.params is enabled. True by default.

  # It can be set to an array that will enable params authentication only for the

  # given strategies, for example, `config.params_authenticatable = [:database]` will

  # enable it only for database (email + password) authentication.

  # config.params_authenticatable = true

 

  # Tell if authentication through HTTP Basic Auth is enabled. False by default.

  # It can be set to an array that will enable http authentication only for the

  # given strategies, for example, `config.http_authenticatable = [:token]` will

  # enable it only for token authentication.

  # config.http_authenticatable = false

 

  # If http headers should be returned for AJAX requests. True by default.

  # config.http_authenticatable_on_xhr = true

 

  # The realm used in Http Basic Authentication. "Application" by default.

  # config.http_authentication_realm = "Application"

 

  # It will change confirmation, password recovery and other workflows

  # to behave the same regardless if the e-mail provided was right or wrong.

  # Does not affect registerable.

  # config.paranoid = true

 

  # By default Devise will store the user in session. You can skip storage for

  # :http_auth and :token_auth by adding those symbols to the array below.

  # Notice that if you are skipping storage for all authentication paths, you

  # may want to disable generating routes to Devise's sessions controller by

  # passing :skip => :sessions to `devise_for` in your config/routes.rb

  config.skip_session_storage = [:http_auth]

 

  # ==> Configuration for :database_authenticatable

  # For bcrypt, this is the cost for hashing the password and defaults to 10. If

  # using other encryptors, it sets how many times you want the password re-encrypted.

  #

  # Limiting the stretches to just one in testing will increase the performance of

  # your test suite dramatically. However, it is STRONGLY RECOMMENDED to not use

  # a value less than 10 in other environments.

  config.stretches = Rails.env.test? ? 1 : 10

 

  # Setup a pepper to generate the encrypted password.

  # config.pepper = "*********************************************************************************************************"

 

  # ==> Configuration for :confirmable

  # A period that the user is allowed to access the website even without

  # confirming his account. For instance, if set to 2.days, the user will be

  # able to access the website for two days without confirming his account,

  # access will be blocked just in the third day. Default is 0.days, meaning

  # the user cannot access the website without confirming his account.

  # config.allow_unconfirmed_access_for = 2.days

 

  # If true, requires any email changes to be confirmed (exactly the same way as

  # initial account confirmation) to be applied. Requires additional unconfirmed_email

  # db field (see migrations). Until confirmed new email is stored in

  # unconfirmed email column, and copied to email column on successful confirmation.

  config.reconfirmable = true

 

  # Defines which key will be used when confirming an account

  # config.confirmation_keys = [ :email ]

 

  # ==> Configuration for :rememberable

  # The time the user will be remembered without asking for credentials again.

  # config.remember_for = 2.weeks

 

  # If true, extends the user's remember period when remembered via cookie.

  # config.extend_remember_period = false

 

  # Options to be passed to the created cookie. For instance, you can set

  # :secure => true in order to force SSL only cookies.

  # config.rememberable_options = {}

 

  # ==> Configuration for :validatable

  # Range for password length. Default is 6..128.

  # config.password_length = 6..128

 

  # Email regex used to validate email formats. It simply asserts that

  # an one (and only one) @ exists in the given string. This is mainly

  # to give user feedback and not to assert the e-mail validity.

  # config.email_regexp = /\A[^@]+@[^@]+\z/

 

  # ==> Configuration for :timeoutable

  # The time you want to timeout the user session without activity. After this

  # time the user will be asked for credentials again. Default is 30 minutes.

  # config.timeout_in = 30.minutes

 

  # If true, expires auth token on session timeout.

  # config.expire_auth_token_on_timeout = false

 

  # ==> Configuration for :lockable

  # Defines which strategy will be used to lock an account.

  # :failed_attempts = Locks an account after a number of failed attempts to sign in.

  # :none            = No lock strategy. You should handle locking by yourself.

  # config.lock_strategy = :failed_attempts

 

  # Defines which key will be used when locking and unlocking an account

  # config.unlock_keys = [ :email ]

 

  # Defines which strategy will be used to unlock an account.

  # :email = Sends an unlock link to the user email

  # :time  = Re-enables login after a certain amount of time (see :unlock_in below)

  # :both  = Enables both strategies

  # :none  = No unlock strategy. You should handle unlocking by yourself.

  # config.unlock_strategy = :both

 

  # Number of authentication tries before locking an account if lock_strategy

  # is failed attempts.

  # config.maximum_attempts = 20

 

  # Time interval to unlock the account if :time is enabled as unlock_strategy.

  # config.unlock_in = 1.hour

 

  # ==> Configuration for :recoverable

  #

  # Defines which key will be used when recovering the password for an account

  # config.reset_password_keys = [ :email ]

 

  # Time interval you can reset your password with a reset password key.

  # Don't put a too small interval or your users won't have the time to

  # change their passwords.

  config.reset_password_within = 6.hours

 

  # ==> Configuration for :encryptable

  # Allow you to use another encryption algorithm besides bcrypt (default). You can use

  # :sha1, :sha512 or encryptors from others authentication tools as :clearance_sha1,

  # :authlogic_sha512 (then you should set stretches above to 20 for default behavior)

  # and :restful_authentication_sha1 (then you should set stretches to 10, and copy

  # REST_AUTH_SITE_KEY to pepper)

  # config.encryptor = :sha512

 

  # ==> Configuration for :token_authenticatable

  # Defines name of the authentication token params key

  # config.token_authentication_key = :auth_token

 

  # ==> Scopes configuration

  # Turn scoped views on. Before rendering "sessions/new", it will first check for

  # "users/sessions/new". It's turned off by default because it's slower if you

  # are using only default views.

  # config.scoped_views = false

 

  # Configure the default scope given to Warden. By default it's the first

  # devise role declared in your routes (usually :user).

  # config.default_scope = :user

 

  # Set this configuration to false if you want /users/sign_out to sign out

  # only the current scope. By default, Devise signs out all scopes.

  # config.sign_out_all_scopes = true

 

  # ==> Navigation configuration

  # Lists the formats that should be treated as navigational. Formats like

  # :html, should redirect to the sign in page when the user does not have

  # access, but formats like :xml or :json, should return 401.

  #

  # If you have any extra navigational formats, like :iphone or :mobile, you

  # should add them to the navigational formats lists.

  #

  # The "*/*" below is required to match Internet Explorer requests.

  # config.navigational_formats = ["*/*", :html]

 

 # The default HTTP method used to sign out a resource. Default is :delete.

  config.sign_out_via = :delete

 

  # ==> OmniAuth

  # Add a new OmniAuth provider. Check the wiki for more information on setting

  # up on your models and hooks.

  # config.omniauth :github, 'APP_ID', 'APP_SECRET', :scope => 'user,public_repo'

 

  # ==> Warden configuration

  # If you want to use other strategies, that are not supported by Devise, or

  # change the failure app, you can configure them inside the config.warden block.

  #

  # config.warden do |manager|

  #   manager.intercept_401 = false

  #   manager.default_strategies(:scope => :user).unshift :some_external_strategy

  # end

 

  # ==> Mountable engine configurations

  # When using Devise inside an engine, let's call it `MyEngine`, and this engine

  # is mountable, there are some extra configurations to be taken into account.

  # The following options are available, assuming the engine is mounted as:

  #

  #     mount MyEngine, at: "/my_engine"

  #

  # The router that invoked `devise_for`, in the example above, would be:

  # config.router_name = :my_engine

  #

  # When using omniauth, Devise cannot automatically set Omniauth path,

  # so you need to do it manually. For the users scope, it would be:

 # config.omniauth_path_prefix = "/my_engine/users/auth"

End

 

Can you help me?

For anyone who's searching for this - find yourself an ldap guy who can guide you.  My app was living on a linux box which reaches upstream to Microsoft AD for ldap.  As such, the attribute 'cn' is not valid - AD kept responding 'invalid' whenever I tried to bind.  When I changed it to sAMAccountName in ldap.yml, it started working immediately!  I could have also used uid, I suppose.  So, there was nothign wrong with this gem - only my configuration.
