ldap 7.x-1.0-beta12

I am new to LDAP server/authentication. I have scoured the internet and forums to try and trouble shoot and have made little progress.

I have a Drupal 7.15 instance installed successfully.
I loaded ldap 7.x-1.0-beta12 and configured the server, enabled it and configured and saved the authentication.These are the only 2 modules required as it is simply an ACL to the corproate LDAP for username/password.

Non HTTPS connection.

I intend to create Drupal users based on the LDAP user so I have it in mixed mode.

When testing the LDAP server, I do not get any response at all. No green messages, etc. No red error messages. Some times I get "No Entry Returned." message at the bottom above the test button.

I am testing iwth the default 7.15 default theme Bartik 7.15.

I can access the LDAP because I have a php script I can run in native mode outside of Drupal abd get authrnticated just fine. Sane server, same web site just outside of Drupal running as a peer web service.

Here are my LDAP server settings:

Server Properties

sid =
name =
status = 1
ldap_type = default
address =
port = 389
tls = 0
bind_method = 4
basedn = Array ( [0] => OU=User Accounts,dc=,dc=local )
binddn =
user_dn_expression = cn=%username,%basedn
user_attr = sAMAccountName
account_name_attr =
mail_attr =
mail_template =
unique_persistent_attr =
allow_conflicting_drupal_accts = 0
ldap_to_drupal_user =
testing_drupal_username =
group_object_category =
search_pagination = 0
search_page_size = 1000

Project specific information is masked iwth .

Use Start-TLS is unchecked.
Have tried both Bind with user credentials and anonymous bind search.
Using sAMAccountName as authname attribuite as this is Active Directory.
Expression for using DN is cn=%username,%basedn
Not using LDAP Groups or pagination.

I enter my Testing Drupal Username as the one in the LDAP which does not yet exist in Drupal. I am logged into Drupal as admin.

Hit the test button and nothing happens.

Any ideas or direction?

Thank you.
