SSPI/Kerberos support for ODBC on Windows 2008 Server

I have my Windows 2008 stand-alone server configured so I can log on using
my MIT Kerberos credentials. I have an SSPI enabled PUTTY which will allow
single-sign-on with Kerberos. This much is working correctly.

My question - does the current ODBC driver support this type of 'native'
configuration on Windows? By that, I mean I haven't installed anything from
MIT on the Windows machine, I have simply run these commands:

ksetup /setdomain DOMAIN.TLD

ksetup /addkdc DOMAIN.TLD host.domain.tld

ksetup /setcomputerpassword xxxxx

ksetup /mapuser user user(at)DOMAIN(dot)TLD

Of course the needed principals have been created on the KDC.

When I test the connection, I get the following error:

pg_krb5_init: krb5_cc_get_principal: No credentials cache found

Thanks
