![]() ![]() You should never create local Linux accounts in the range you reserve for Winbind in this way. This range is given as two numbers separated by a dash, as in 2000-5000. Thus, you can give Winbind a range of local UID numbers to use for the accounts it handles. NT domains use a number called a Security Identifier (SID) for a similar purpose however, the two numbers aren't identical. Linux uses UIDs internally for tracking users. This parameter works much like winbind enum users, but it affects system calls for enumerating groups rather than users. Thus, if the programs you run on a system don't require this support, setting this parameter to No can improve performance. Winbind supports these features if this parameter is set to Yes (the default), but this support can be slow. Linux provides certain system calls that enable programs to enumerate users on a system. The default character is a backslash ( \). This parameter specifies a character that separates domain names from usernames when winbind use default domain = No. Doing this is safest when you have just one domain or when you're sure that no usernames are duplicated on multiple domains. If you set this Boolean parameter's value to Yes, though, Winbind omits the domain name from usernames, which results in shorter and more sensible usernames. This feature enables you to maintain multiple domains and support users with duplicate usernames in these domains without causing conflicts. Ordinarily, Winbind returns Linux usernames that are based on a combination of the NT domain name and the NT username. These parameters set values for information required by Linux accounts but not provided by the domain controller: In addition to these options, which are the same as those you must set for any Samba domain member server, you may want to set several other global parameters. It provides somewhat better security on your LAN because it uses the extremely robust Kerberos authentication system. If your domain controller supports AD, you can set security = ADS instead of security = Domain, but this configuration requires setting additional options and can be finicky. The security parameter must be set to Domain, and encrypt passwords must be set to Yes. #Smbconf review passwordYou should adjust the values of the workgroup and password server parameters for your network, of course. Most notably, you should set the workgroup, security, encrypt passwords, and password server global options: workgroup = GREENHOUSE security = Domain encrypt passwords = Yes password server = 192.168.1.1 You should configure the smb.conf file on the domain member server much as you would for any Samba server on a domain, as described in Chapter 3. If you use a Samba server as the domain controller, it requires its own configuration, which need not include most of the options described here. This configuration occurs on the domain member serverthe Linux system you want to configure to use a domain controller's account database. Running the Winbind daemon is also critically important to getting the system running. #Smbconf review how toThus, you must know how to set these Samba options. The main Winbind options appear in smb.conf (although, as described earlier, some options are set in the PAM and NSS configuration files, as well). Much of the configuration of Winbind is done using Samba. ![]()
