Binary package “winbind” in ubuntu precise

Samba nameservice integration server

 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 NT4-style domain controller, and can integrate with both NT4 domains
 and Active Directory realms as a member server.
 This package provides winbindd, a daemon which integrates authentication
 and directory service (user/group lookup) mechanisms from a Windows
 domain on a Linux system. User/group lookups are configured via
 /etc/nsswitch.conf, and authentication is integrated using the winbind
 module for PAM.
