Cerficate for kdc

[Alberto Fondi <alberto.fondi@lnf.infn.it>]

Hi group,

    this time my question is: i'm using heimdal and pkinit, however i 
want to use a pem certicate for the kdc protected with a pem passphare, 
but when i start the kdc it doesn't ask for the passphrase and in the 
log the following message appear: PKINIT: failed to load: open 
/var/heimdal/kdc.conf: No such file or directory

Where i must specify the passphrase?

Thanks
