EAP-TLS computer authentication on Aerohive Radius "host/" problem

I would like to use EAP-TLS with computer authentication with the aerohive radius on the access point.
The problem is, windows 7 and 10 is sending the common name (CN) of the computer certificate with a leading host/ e.g. host/computer1.

The problem is, you can not revoke the access if you loose a certificate because of the following reasons:

1. Aerohive AAA Server Settings are not helpfull:
Option Query database to check if the user exist -> For TLS Authentication:
With this setting the EAP-Identity of the Client needs to be in the radius database. This option is useless for the security because the client can send an arbitrarily EAP-Identity.
So for security you also need "Check the common name in the certificate against the user for TLS authentication". But this dos not work for computer authentication because windows send host/CN.

2. It looks like the aerohive radius dosn't support Certificate Revocation List (CRL). So revoking the certificate is useless. Can somebody confirm?
This is so annoying, because the manual says, you need a CRL for the security!


Has somebody a solution for the problem?
Can I remove the host/ in the aerohive radius?
Can I remove the host/ in the EAP-Identity from windows machine?

Please Aerohive, care about security and implement CRL in you radius or give the user the option to remove the host/ prefix.
Also it would make much more sense, if you compare the CN of the computer certificate with the radius database. This would also solve the problem.
