[Samba] Samba + ADS + Kerberos ticket problem

[Michael Fernández M]

Hi...

I have working a setup with samba + kerberos + ads

Everything works great... BUT.... every time i reboot the machine the
kerberos ticket.. is lost, so I have to do:
kinit administrator at DOMAIN  and
net join ads administrator%pass_domain_admin 

And, all the setup works again...

Somebody knows how to solve this?

Thanks a lot for any input.

Michael.-
