winbind 3.0.25-1ubuntu1 (amd64 binary) in ubuntu gutsy

 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.)
 .
 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.
