I just installed the 'Kerio Active Directory Extensions' on my Windows 2000 Server. In the KMS admin console under 'Advanced Options' and the 'Security Policy' tab I have the 'Allow NTLM authentication for users with Kerberos authentication (for Active Directory users)' checked. I create a new user and go through the process (I see the KMS setup), but the users can't authenticate. I go to the KMS admin console and I see the user. It shows they are setup to use LDAP, but it won't authenticate.

Am I missing something? Is there an issue with KMS & Active Directory?

My domain controller and my mail server are on two separate servers. I don't know if that makes any difference.

Thanks in advance!

It should work. A couple of things that have been discussed in the past to help get it working are:

Check and make sure NTLM is checked as an Enabled Authentication Method (Also on the Security Policy tab).

In the Domain properties, on the Directory Service tab, try using the FQDN of the Active Directory server. If that fails, try the NetBIOS name instead.

On the client machine, make sure Secure Password Authentication is checked in the Account Settings.

In the debug log, enable Authentication modules and Directory service lookup to track down any further issues.

I was not using the 'Secure Password Authenitcation' on the client. I was manually typing in the username and password. I'm glad it's just my ignorance and not a bug!

Are there any other issues I should be aware of while using Active Directory (LDAP/NTLM) for authentication?

Thanks for the quick response!

I maybe spoke too soon. I am now having an issue with the account I set up to use AD/NTLM. I can't use that account to login to webmail. Is there something I'm missing?
