What are the requirements for configuring a Samba file server to work in Active Directory mode? (Choose THREE correct answers.)

To configure a Samba file server to work in Active Directory mode, several critical steps and configurations are required to ensure proper integration and functionality within the Active Directory (AD) environment.

Joining the domain using the command 'net ads join' is crucial because this action authenticates the Samba server to the Active Directory domain. By successfully joining the domain, the Samba server obtains the necessary credentials and security context to interact with domain resources. This step is foundational, as it establishes the relationship between the Samba server and the Active Directory, allowing for permissions and access control to function correctly.

Specifying a realm in the smb.conf file is also a requirement. The realm corresponds to the Kerberos realm that your Active Directory operates under. This setting in the configuration file helps Samba understand the domain it is interacting with and ensures that the authentication processes are aligned with those used by the Active Directory. Properly setting the realm ensures that Kerberos authentication can be utilized effectively for services provided by the Samba server.

Ensuring there is no clock drift between the systems in the Active Directory is another important requirement. Active Directory relies heavily on time synchronization for authentication processes, particularly those using Kerberos authentication. If there is significant time difference between the Samba server and the Active Directory domain controller, authentication
