Think you'll find that settings is controlled under the Domain Controller Group Policy Object.

Enabling anonymous LDAP operations
Launch ADSI Edit (part of support tools) and navigate to:
CN=Directory Service,CN=Windows NT,CN=Services,
Where  is the root domain of your forest (in my case this is DC=antid0t,DC=net)

Right click the "CN=Directory Services" container, choose "Properties" from the context menu and scroll down to the dsHeuristics attribute


If the attribute is not set (has no value), fill in "0000002" in the value field. The last (seventh) character is the one that controls the way you can bind to LDAP service. "0" or no seventh character means that anonymous LDAP operations are disabled. Setting the seventh character to "2" permits anonymous operations (you are still subject to Access Control Lists of the objects in AD)

As per my first post, this feature is set under the 'Default Domain Controllers Policy'.

Under Computer Configuration/Policies/Windows Settings/Security Settings/Local Policies/Security Options

The setting is 'Domain Controller: LDAP server signing requirements'

If you change the value under this group policy, it will update all of your AD servers.  Once you've done the change, run 'gpupdate /force' on your AD server to apply the change otherwise wait upto 90 minutes for it to refresh.

Using ADSI edit is not the correct way of setting this value on a DC.
