how to automount a cifs share from Samba4

[steve]

Hi

The Administrator needs a ticket to mount the share. The idea is that if 
anyone hits the automounter, the ticket is already there and no password 
prompt appears.

I've tried this at startup:
k5start Administrator -f /etc/admin.keytab
where admin.keytab contains the extracted Administrator key.

It's OK, but maybe you guys could point out any security risks and/or 
suggest a better method.

Cheers,
Steve
