XADM: KM Server Issues V1 Certificate When Configured to Issue V3 Only

ID: Q231307

The information in this article applies to:

SYMPTOMS

If you configure a Key Management (KM) server to issue X.509 V3 certificates only, the server may still issue V1 certificates when e-mail clients request them. This problem is known to occur with the Microsoft Exchange client versions 4.0 and 5.0, and Microsoft Outlook 97, but the problem can occur with any e-mail client that only uses V1 certificates.


CAUSE

When an e-mail client requests a certificate from a KM server, the server does not verify that the request is compatible with its current configuration.


RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack that contains this fix.
