ACS 4.2.1 - PEAP Machine Authentication - Hostname different from PC account name in AD


I don't really know, whether this issue has been asked before.

I have to configure PEAP Authentication with ACS 4.2.1 for Windows against Active Directory.

ACS ist Member of AD Domain xyz.domainname. The PC account is located in an OU of xyz.domainname.

Hosts get via DHCP a hostname as dhcp.domainname. This also is the name the machine uses for AAA request.

User authentication works fine, because the user account also is hosted in xyz.domainname.

The host authentication fails, because dhcp.domainname is a DNS domain only but no Windows AD subdomain.

Does anybody knows a solution for this special constellation?

Is it possible to strip or rewrite the domain suffix in any way during the authentication process?
