Q231307: XADM: Server Issues V1 Certificate When Configured for V3 Only

Article: Q231307
Product(s): Microsoft Exchange
Version(s): winnt:5.5
Operating System(s): 
Keyword(s): exc55 EXC55SP3Fix
Last Modified: 30-SEP-1999

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------


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
==========

To resolve this problem, obtain the latest service pack for Exchange Server
version 5.5. For additional information, please see the following article in the
Microsoft Knowledge Base:
