NIS: Network Information Service

Quote:
A NIS/YP system maintains and distributes a central directory of user and group information, hostnames, e-mail aliases and other text-based tables of information in a computer network. For example, in a common UNIX environment, the list of users for identification is placed in /etc/passwd, and secret authentication hashes in /etc/shadow. NIS adds another “global” user list which is used for identifying users on any client of the NIS domain.
what is the difference from just doing it 1 by 1?

You can build script that adds all 20 users, and then copy/execute the script on all 50 servers using ssh. This will reduce your effort and eliminate the possibility of typos causing certain servers to have different setups.

But again if the users need to be kept in sync form this date forward NIS/YP is the preferred solution.

nissetup(1M)                                              System Administration Commands                                              nissetup(1M)

NAME
nissetup - initialize a NIS+ domain SYNOPSIS
/usr/lib/nis/nissetup [-Y] [domain] DESCRIPTION
nissetup is a shell script that sets up a NIS+ domain to service clients that wish to store system administration information in a domain named domain. This domain should already exist prior to executing this command. See nismkdir(1) and nisinit(1M). A NIS+ domain consists of a NIS+ directory and its subdirectories: org_dir and groups_dir. org_dir stores system administration informa- tion and groups_dir stores information for group access control. nissetup creates the subdirectories org_dir and groups_dir in domain. Both subdirectories will be replicated on the same servers as the parent domain. After the subdirectories are created, nissetup creates the default tables that NIS+ serves. These are auto_master, auto_home, bootparams, cred, ethers, group, hosts, mail_aliases, netmasks, networks, passwd, protocols, rpc, services, and timezone. The nissetup script uses the nistbladm(1) command to create these tables. The script can be easily customized to add site specific tables that are created at setup time. This command is normally executed just once per domain. While this command creates the default tables, it does not initialize them with data. This is accomplished with the nisaddent(1M) command. It is easier to use the nisserver(1M) script to create subdirectories and the default tables. OPTIONS
-Y Specify that the domain will be served as both a NIS+ domain as well as an NIS domain using the backward compatibility flag. This will set up the domain to be less secure by making all the system tables readable by unauthenticated clients as well. ATTRIBUTES
