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

The `net ads join` command is essential to create and configure the Samba server's machine account in Active Directory, allowing it to become a member of the domain.

The `realm` parameter in `smb.conf` specifies the Kerberos realm that Samba should use for authentication against Active Directory, which is critical for successful domain operations.

Accurate time synchronization between the Samba server and the Active Directory domain controllers is a fundamental requirement for Kerberos authentication to prevent authentication failures due to time skew.

While Winbind is used for user/group resolution in ADS mode, the `-krb5` option is not a standard or necessary command-line argument for configuring Winbind for Active Directory integration; Winbind handles Kerberos automatically when properly configured via `smb.conf`.

The `pdbedit` command manages Samba's local user database (`smbpasswd`). In Active Directory mode, user accounts are authenticated and managed by Active Directory itself, not locally created via `pdbedit` on the Samba server.
