Client Authentication Fails Connecting to Netscape Server

• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server, Enterprise Edition version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

Connecting to a Netscape server that requires client authentication may fail. After trying to connect, the server returns an "invalid certification" alert or just drops the socket connection.

CAUSE

Recent versions of the enrollment control (Xenroll.dll) place the intermediate certificates in the "CA" certificate store, rather than in the "MY" or "ROOT" stores like schannel expects (the "CA" store had not been invented when this schannel was written).

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, please see the following article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed this to be 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.
