samba - Oct 2008 - samba + kerberos

Hello
I set samba to use kerberos password backend  (without ldap)

   use kerberos keytab = yes
   security = user
   realm = DOM.COM
   encrypt passwords = yes
   unix password sync = no

And generally it works ...

when (on the linux client) I put

kinit
and type the password
and then
smbclient -k //smbserv/files

I am logged in and I can see the files

But I would like to mount it automatically (for ex. in /etc/fstab)
so how to do it?
In usual samba without kerberos I can write password and username in mount
options - but it is different situation.

And next question - what if I would like to use windows client?

thanks for any help
