Use of nis server in Linux

Question

Describe use of nis server in Linux?

Answer 1

The main reason of NIS is centralizing the authentication database.

For example:

Usually while a user attempt to login to the machine it will contact the password, shadow and group files for user’s authentication, in case of user need to access his/her account across the network we have to update user’s information all these files in each of the machine in the network. It is little bit tricky to organize multiple users’ information in all the machines in the network.

NIS server will behave as central server for user authentication and all other machines will contact the NIS server for the user’s authentication information.

Ensure all the machines in your network should be in the similar domain. NIS will work only in single domain.
