The Samba service that handles the membership of a file server in an Active Directory domain is winbindd. Winbindd is a daemon that provides a number of services to the Name Service Switch (NSS) capability of the system, such as resolving user and group information from a Windows NT server and authentication. Winbindd can also be used to join a Samba file server to an Active Directory domain and authenticate domain users to access the file shares12 References:

The status parameter in an OpenVPN server configuration file specifies the name of a file where OpenVPN writes information about the current status of the VPN tunnel, such as the time, bytes sent and received, and the IP address and port of each connected client. This file can be used to monitor the VPN activity and troubleshoot any issues. The file does not contain any information about errors and warnings generated by the openvpn daemon, as those are written to the log file specified by the log or log-append parameter. The file also does not contain any historical information about the clients who have connected at some point, as it only shows the current state of the VPN tunnel.

Samba cannot use /etc/passwd and /etc/shadow directly because they store passwords in a different format than CIFS. CIFS passwords are encrypted using a one-way hash function, while Unix passwords are encrypted using a two-way cipher. Therefore, Samba needs a separate password file that stores the CIFS passwords in a compatible format. This file is usually called smbpasswd and can be created or updated using the smbpasswd command123 References:

The rpc.idmapd service is a new component of NFSv4 that does not exist in NFSv3. It is responsible for mapping user and group IDs between the NFS client and server, using string names instead of numeric values. This allows for better security and compatibility across different systems. The rpc.idmapd service runs on both the NFS client and server and communicates with each other using the NFSv4 protocol. The other services, rpc.statd, nfsd, and rpc.mountd, are common to both NFSv3 and NFSv4, although they have some differences in functionality and behavior. References: 1, 2, 3
