winbind4 4.0.0~alpha15~git20110124.dfsg1-2ubuntu1 (i386 binary) in ubuntu natty

 The Samba software suite is a collection of programs that
 implements the SMB protocol for unix systems, allowing you to serve
 files to Windows, NT, OS/2 and DOS clients, as well as
 run as a domain controller for Active Directory.
 .
 These packages contain snapshot versions of Samba 4, the next-generation
 version of Samba.
 .
 This package provides the winbindd daemon, which provides a
 service for the Name Service Switch capability that is present
 in most modern C libraries (like the GNU C Library - glibc.). Please
 note that the functionality of this version of winbind is behind on that
 of the winbind package.
 .
 The service provided by winbindd is called `winbind' and
 can be used to resolve user and group information from a
 Windows NT server. The service can also provide authentication
 services via an associated PAM module.
