Hello, We just updated samba from 2.2.8 to 3.0.0. Now looks like we got some issues with the authentication system. Server in domain A. Create private share on server. If a windows client doesn't join the domain A, I was able to map the server's private share by give user name and password on this client. The difference between 2.2.8 and 3.0.0 is how to give the user name. In 2.2.8, it takes "Domain\Username". However, in 3.0.0, only username, no domain name, will work. Is that right? I thought any client from outside the domain suppose to give domain name AND user name when they login. I knew samba 3.0.0 changed the authentication system. But I don't know the user from outside the domain can login without given domain name. Is it supposed to work this way or a bug? Any reply is highly appreciated! smb.conf like: [disk0] path=/disk0 writeable=Yes public=Yes browseable=Yes available=Yes case sensitive=No [disk1] path=/disk1 writeable=Yes browseable=Yes available=Yes case sensitive=No Thanks a lot!
