Readme Notes for Certificate Server Update

Highlights
----------

This update to the Microsoft Certificate Server applies to version 1.0 as
shipped with the Microsoft Windows NT Option Pack. The highlights of this
update are as follows.

 - Teletex Encoding. Data encoded as teletex in a certificate request
   will be encoded as teletex data in the certificate issued. Formerly,
   these data would have been encoded as unicode in the certificate issued.

 - Serial Number. Serial numbers generated during certificate issuance
   will always be positive. Formerly, these serial numbers were
   allowed to be negative. While this was consistent with X.509, it
   caused problems for certain restrictive mail clients.

 - Backup/Restore. Specific backup requests are now supported,
   specifically for backing up keys and certificates. A Microsoft
   Knowledge Base article is available describing the procedural
   aspects of using this capability.

Be sure you are familiar with the release notes for the Certificate Server
originally distributed with the Windows NT Option Pack. Also, be sure you
get the following Microsoft Knowledge Base article on backup/restore of
keys and certificates.

hierarchies for use with Microsoft Exchange from a white paper titled
