Title:
  libnss_wins always performs a broadcast lookup.

Status in samba package in Ubuntu:
  Triaged
Status in samba package in Debian:
  Fix Released

Bug description:
  Binary package hint: samba

  I'm trying to get my workstation to use our Windows NT4 domain
  lookups, though I don't want to join the domain. To this end, I'm
  setting up WINS lookups.

  I have the "wins server" set to my WINS server's IP address in
  /etc/samba/smb.conf, as well as "name resolve order = wins". I've
  added WINS to the name services

  $ grep wins /etc/nsswitch.conf 
  hosts:          files mdns4_minimal [NOTFOUND=return] wins dns mdns4

  The idea is that names should be checked against the WINS server
  first, and if that fails, they should be tried against DNS. However,
  all DNS lookups are now noticeably slow (around 0.8 seconds), since
  it's performing a broadcast search, which I can see in Wireshark: on a
  successful query, it checks the given WINS server. On an unsuccessful
  query, it checks the given WINS server, then sends three packets to
  the network broadcast address.

  libnss_wins should respect the settings in smb.conf (since it *is*
  reading that file to get the WINS server address), and give up without
  trying time-consuming broadcasts.
