libnss-nisplus 1.3-0ubuntu3 (amd64 binary) in ubuntu groovy

 This package provides a Name Service Switch that allows your NIS+ server
 act as a name service. This means providing user account information,
 group id's, host information, aliases, netgroups, and basically anything
 else that you would normally get from /etc flat files.
 .
 This module was formerly part of glibc, but is now standalone to be able
 to link against TI-RPC for IPv6 support.
