I have a question. What is the requirement of integrate ACS 4.2 Appliance and AD about CA server? it has to be windows 2003 server enterprice o windows 2008 enterprice? or it can be windows 2003 and 2008 stand alone? another question is about multi domain, i have domain father and children. the installation of CA Server is in domain father to enable 802.1x with AD with all domain children integrate? or I can be install the CA server in the server of domain children and is it work (CA server installed in server in domain child and it working all domains child and father)?

I think that you are mixing a lot of different concepts.

ACS 4.2 can integrate with 2003 or 2008 for AD authentication of users.

If you talk about CA verification (like with EAP-TLS), then the domains don't matter at all.

If your father domain is the "father" CA as well that issued the child domain CA, then all the certificates issued by the child domain will be trusted as well as long as ACS trusts the root.
