Full Discussion: Change to NIS netgroup definition in upcoming Internet Draft
Top Forums UNIX for Advanced & Expert Users Change to NIS netgroup definition in upcoming Internet Draft Post 302800169 by MadeInGermany on Monday 29th of April 2013 06:29:16 AM

Yes, many companies have NIS still.
But I haven't met any that uses the netgroup domain field.
NIS can handle a thousand simultaneous user logins, and even 10thousand simultaneous logins by enabling netid lookup in /etc/default/nss.
At least the Sun/Solaris NIS server (and e.g. HP-UX who licenced from Sun/Oracle) has support for automatically building the netid map.
I have only seen small LDAP environments. And one big NIS+ environment.

ypwhich(1)							   User Commands							ypwhich(1)

NAME

       ypwhich - return name of NIS server or map master

SYNOPSIS

       ypwhich [-d domain] [ [-t] -m  [mname] | [-Vn] hostname]

       ypwhich -x

DESCRIPTION

       ypwhich	returns  the  name  of	the  NIS server that supplies the  NIS name services to a NIS client, or which is the master for a map. If
       invoked without arguments, it gives the NIS server for the local machine.  If hostname is specified, that machine is queried  to  find  out
       which NIS master it is using.

       Refer to ypfiles(4) for an overview of the  NIS name services.

OPTIONS

       -d domain       Use domain instead of the default domain.

       -t	       This option inhibits map nickname translation.

       -m mname        Find  the  master  NIS server for a map.  No hostname can be specified with -m. mname can be a mapname, or a nickname for a
		       map. When mname is omitted, produce a list of available maps.

       -x	       Display the map nickname translation table.

       -Vn	       Version of  ypbind, V3 is default.
