samba 2:4.17.7+dfsg-1ubuntu2.1 (amd64 binary) in ubuntu lunar

 Samba is an implementation of the SMB/CIFS protocol for Unix systems,
 providing support for cross-platform file and printer sharing with
 Microsoft Windows, OS X, and other Unix systems. Samba can also function
 as an Active Directory or NT4-style domain controller, and can integrate
 with Active Directory realms or NT4 domains as a member server.
 .
 This package provides the components necessary to use Samba as a stand-alone
 file and print server or as an NT4 domain controller. For use in an NT4
 domain or Active Directory realm, you will also need the winbind package.
 To use samba as an Active Directory domain controller (AD DC), please install
 samba-ad-dc package.
 .
 This package is not required for connecting to existing SMB/CIFS servers
 (see smbclient) or for mounting remote filesystems (see cifs-utils).
