samba - Aug 2007 - Samba using linux root under ADS mode

hi all am having a problem connecting to my samba server on linux using the
host's root account. I have created a local smbpassword for root but am
unable to connect to any shares with it.

my primary reason is that am trying to get cupsaddsmb program to copy up driver.

so I tested with smb client and my smbd is not allowing root connections any
advice?

thanks

Damien
