[Samba] Samba Nfs4 kerberos intergation

[rmostert]

Hi,
I have two linux machines whom are  currently  linked via nfs3. A 
directory form one machine is mounted on the other, and this directory 
is part of a samba share. This setup works fine, except for the 16 
groups limitation. To overcome this I have upgrades to nfs4, and use 
mit-kerberos.

How can I tell samba to kinit to the current user so that the mounted 
nfs4 share is read with the right permissions?

Thanks alot!
