I'm using samba-2.0.7 on RH-6.0 . Now I'm using /etc/smbpasswd to authenticate users. I wonder if samba can use one's NT account (including password) to authenticate him?(That's to say,samba redirect all authentication to a NT PDC). I have the following setting in [global] section: security = server password server = * -------------------------- Every time I must provide password in smbpasswd to be authenticated instead of my NT password. I do not want to join a NT domain! BTW:How do I know accuratly which is the PDC in our subnet?
