winbind 2:4.3.9+dfsg-0ubuntu1 (armhf binary) in ubuntu yakkety

 Samba is an implementation of the SMB/CIFS protocol for Unix systems,
 providing support for cross-platform file sharing with Microsoft Windows, OS X,
 and other Unix systems. Samba can also function as a domain controller
 or member server in both NT4-style and Active Directory domains.
 .
 This package provides winbindd, a daemon which integrates authentication
 and directory service (user/group lookup) mechanisms from a Windows
 domain on a Linux system.
 .
 Winbind based user/group lookups via /etc/nsswitch.conf can be enabled via
 the libnss-winbind package. Winbind based Windows domain authentication can
 be enabled via the libpam-winbind package.
