    Hi,

  I have third party CA issuing certificates for users in Windows 2003
Enterprise based Active Directory. Everything works fine, I can logon to AD
without problems, but I would like to assing certificates to users accounts
to make them available for other domain members. How to achieve it ? Is is
possible ?

    regards,
Martin
