Good day, I apologise for the long post but I think all is relevant. Any help would be appreciated. My smb.conf global section at the bottom. Thanks. Has anyone set up Samba 3 using winbindd to authenticate on 2003 Active Directory? Winbind appears to working correctly. Joined the domain without an error However when trying to connect to samba server it requests a logon and denies whatever I enter as Username or password. I have also noticed that when trying to use the netbios name of the server ( \\server) it does not want to authenticate me at all. When using the FQDN (\\server.domain.co,za) it again requests a username and password, when I enter my AD username and password it does not authenticate me (wrong username or password), however when using smbpasswd password it lets me in. Is it still using the incorrect authentication method ? Why doesnt it like the netbios name ?? It seems to be working perfectly on NT4.0 machines. Dont have any win9x things lying around to test on. Problem appears to be only with XP 2k and 2003. I have heard that there is smb signing involved with 2003. Is this the case with 2K ? Had a look at messages.
