pkinit patch for heimdalv0.5 with windows 2000 server

[nprasad@embeddedinfotech.com]

Hi
      I was trying out the pkinit patch from
http://meta.cesnet.cz/software/heimdal/pkinit.en.html
The patch works perfectly fine when tested with heimdal kdc
however i have problems with windows 2000 server's kdc
i get the error
"kinit: krb5_get_init_creds: KDC has no support for padata type"
I'm using certificates from disk(no smartcard). I'm using windows 2000
server(not advanced server).
I'm guessing i've problem with my windows 2000 kdc setup. The normal
kinit(password) works fine.
If anyone has any has successfully conifgured windows 2000 server for
pkinit please let me know how to do so.
Thanks
Prasad.
