The reason is that the Web enrollment requests are performed in the
security context of the user, not the computer. The computer has enroll
permissions and not the user. Even if the user were assigned the Read
and Enroll permissions, there is no DNS name in their user account to
populate the subject of the certificate.

You must enable the Offline templates or create a v2 template that
enables the user to provide the subject in the request. This will allow
the user to type the DNS name of the computer and then submit the
request from the Web interface (if they have Read and Enroll permissions
for the cert and are a local Administrator on the computer to install it
in the machine store)
