Hi all, I need to enable smartcard logon (windows server 2003 AD -windows 2003 CA - windows XP SP2 clients) on 2 different domains for the same person with the same smartcard. So what I need is to have - on the same smartcard - 2 certificates, one for the domain1\user01 and one for the domain2\user01 . Of course we have a Microsoft CA server in both domains.Is it possible to do this with my 2003/XP evironment or I need windows vista/windows7 clients and 2008 servers?Many thanks in advance.Best regards.Gabrix01

Hi,IMHO windows vista has the capability of loging to multiple domains / forest using X509HintsNeeded registry.Please take a look at below article. http://technet.microsoft.com/en-us/library/cc721959(WS.10).aspx
