SYMPTOMS

You are unable to securely authenticate to an LDAP server using applications such as Windows Address Book or NetMeeting on the French version of Windows NT 4.0 when using NTLM. The application may fail to read entries and may return an error message.

CAUSE

Because LDAP asks for confidentiality for NTLM, DPA, and MSN authentication packages, it will not work on the French version of Windows NT.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed that this is a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.

MORE INFORMATION

With this fix, LDAP no longer asks for confidentiality when using NTLM.
