Thus far, we've generalized our Samba configuration discussions so that they would apply equally well in either a workgroup or a domain network model. Samba services like WINS and master browser work equally well for workgroups and domains. In this chapter we'll depart from the generalized track and focus specifically on integrating Samba in a Windows domain.

Windows domains are similar to workgroups in that they represent a group of users, services and computers that collectively share a common namespace. Domains differ from workgroups, in that a domain enforces a common security policy and management structure across its membership. Account directory information is stored in a secure central repository called the Security Accounts Manager (SAM). The SAM database is maintained on the primary domain controller and replicated on each of the backup domain controllers (see 3). What this means for the system administrator is that there is a central location for managing the accounts, passwords, access controls and policies for the entire domain. End-users benefit from the domain model in by gaining access to all domain resources via a single logon. Domains improve access security over workgroups because client authentication is performed only once using a secure communication channel with the PDC during domain logon. Once authenticated, client access to resources is governed by applying access controls based on the client's group memberships. Domain groups are a means of categorizing users with similar needs and work profiles. In contrast, each workgroup client maintains a persistent local cache of accounts and passwords required to access network resource. A separate credential cache is created for each active user and stored in the \windows directory as <username>.PWL. Windows opens the cache file using the associated user's logon password as a key. During connection to a network resource, each entry in the user's credential cache is tried until authentication is either accepted or denied. Credentials stored in these cache files are extremely vulnerable to security threats due to the weak encryption employed and their persistent nature across logons by different workstation users.

Domains also offer a means for authorizing access to resources residing in separate domains through trusts. A trust relationship is a link that logically combines two domains into an administrative unit. The trust relationship may be applied one way (domain A trusts domain B, but domain B does not trust domain A) or two ways (domain A and domain B trust each other).

Unlike its extensive WINS and browser implementations, Samba's domain functionality is not quite as feature-inclusive. This is not to say that Samba can't play a part as a client or controller in a domain environment. A Samba server can participate fully as a client in an NT domain. Samba can also operate as a domain controller within limits. Acting as a domain controller in a Windows 9x environment Samba can support domain logons, logon scripts, user profiles, and system policies. Samba doesn't support SAM database replication nor does it "officially" support remote management via Windows NT domain administration tools. Work is under way to provide Samba PDC functionality in a Windows NT client environment. This effort includes support for interoperation with selected Windows NT domain tools. You will find more about Samba PDC development and the availability of experimental source code later in the chapter.

To add a Samba server as a domain member we must create a machine account and password for the server and register it with the domain's PDC. Begin by stopping the smbd and nmbd daemons on the Samba server. Next, update the server's smb.conf file to reflect the attributes of the target domain (Table 10.1). The security parameter should be set to a value of domain. The netbios name and workgroup parameters must identify the server's NetBIOS name and the domain name respectively. The password server parameter should list the name of the PDC as well as any BDC's for the domain. Because domain logon will require the use of an encrypted password, enable the encrypt passwords parameter. Set the machine password timeout interval to indicate how often smbd should change the machine password. The default value is once a week. Table 10.1 Samba Domain Member Parameters
security = domain netbios name = <NetBIOS name> workgroup = <domain name> password server = <PDC BDC1 ... BDCn> encrypt passwords = true machine password timeout = <seconds>
Don't restart Samba yet. Register the Samba server's NetBIOS name as a domain member using Server Manager on the PDC (Figure 10.1). After adding the server name and verifying domain membership, set the machine account password on the Samba server using the smbpasswd command (Example 10.1). The new password will be stored
