Drupal Authentication with ActiveDirectory I'm trying to make Drupal work with ActiveDirectory just for authentication. I'm using Lightweight Directory Access Protocol.  

I always get this message: 


  Warning: ldap_search(): Search: No such object in LdapServer->search() (line 257 of D:\wwwroot\drupal\sites\all\modules\ldap\ldap_servers\LdapServer.class.php).
  Test sandbox-edu LDAP Server Configuration Binding with DN for non-anonymous search (testuser@sandbox.edu). Using password entered in form.
  Successfully bound to server
  Failed to find test user userone by searching on sAMAccountName = user one.
  No such object


Here are the settings of the Server Properties:


sid = SANDBOX_EDU
name = sandbox-edu
status = 1
type = ad
address = LDAP://10.100.100.2
port = 389
tls = 0
bind_method = 1
basedn = Array
binddn = testuser@sandbox.edu
user_dn_expression = cn=%username,%basedn
user_attr = sAMAccountName
mail_attr =
ldap_to_drupal_user =
testing_drupal_username = userone


Can anyone who were able to get this module working with ActiveDirectory show us a sample of the setting?

If there's any other way other than using this module, please also recommend. I really need Drupal to work with ActiveDirectory for authentication because we have many students here.
I have the following set of parameters that allow authentication by Active Directory 2003:

server type: "Active Directory LDAP"
server address: ad.example.com
ldap port: 389
binding method for Searches: Bind with Users Credentials
base DNs for LDAP user entries: cn=users,dc=example,dc=com
username attribute: sAMAccountName
expression for user DN: %username@company.com
email attribute: mail


I think the problem mainly stems from the fact that AD typically does not have the login name in the LDAP DN.
