[Samba] samba 3 and active directory

[Andrea Lorenz]

Hello,

we have integrated our samba service in a Windows active directory domain. Everything running fine.
Now I want to understand the authentification process. What happens when a Windows client maps a 
network drive from the samba server?
Does the Windwos client send its kerberos ticket to the samba server or does it send the username 
and password to the samba server and the samba server creates a kerberos ticket. Does it make any 
difference if the Windows client is part of the domain or if it is not part of the domain.
Does anyone know a book, aritcle or website where I can find out more about this?

Thanks,
Andrea
