libpam-winbind 2:3.5.11~dfsg-2ubuntu3 (armel binary) in ubuntu precise

 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 pam_winbind and nss_winbind, plugins that integrate
 with a local winbindd server to provide Windows domain authentication and
 user/group name lookups to the system; and nss_wins, which provides
 hostname lookups via the WINS and NBNS protocols.
