EAP-TLS machine authentication ACS 5.2

Hi, we have a customer with a wifi deployment aruba 3600 controller based. Corporate SSID authentication is EAP-TLS double machine and user authentication through ACS 4.2 against AD and Microsoft AC PKI infraestructure based; it was working ok. After migrating from ACS 4.2 to 5.2, both authenticacion (machine and user) are reported as succeed by ACS but aruba controller does not recognize machine authentication. It seems that controller sees two authentication users and not an machine followed by and user one. We have revised configuration in detail and it seems correct. We begin thinking it could be a bug . We would apreciate any help. Thanks in advance

Can you elaborate your issue further on the aruba end, is the client not able to access the network or is the most recent username in the aruba client tables showing up as the user account?

thanks,

When eap-tls machine authentication works fine aruba controller keeps the client MAC address in the local-userdb as cached evidence that a good machine authentication has occurred. This client MAC address is kept for a certain amount of time, which is based on the "caching period". It works in this way with acs 4.2 but we never see client MAC with ACS 5.2. However, ACS reports a successful authenication with machine FQDN (it reports RADIS name=host/machine.domain.es and ACS name=machine.domain.es)
