I recently downloaded samba-3.0alpha19 and installed and configured it as a PDC, but I cannot add Windows 2000 client to the samba domain, I get "The parameter is incorrect" message. The same setup was working fine with alpha18. Has anyone tested samba-3.0alpha19 PDC functionality? I tried using ldap backend first and then switched to smbpasswd file but still no luck. Here is my smb.conf [global] workgroup = HEAD2 netbios name = sambapdc server string = Samba 3.0-alpha19 security = USER encrypt passwords = Yes update encrypted = No min passwd length = 5 map to guest = Bad User null passwords = No obey pam restrictions = No password server = * smb passwd file = /usr/local/samba/private/smbpasswd private dir = /usr/local/samba/private use spnego = No domain logons = Yes os level = 64 preferred master = Yes local master = Yes domain master = Yes browse list = Yes enhanced browsing = Yes dns proxy = Yes wins support = Yes fstype = NTFS admin users = administrator log level = rpc_server:5 unicode = No [netlogon] path = /usr/local/samba/lib read only = yes write list = ntadmin __________________________________________________ Do you Yahoo!?
