basic central user authentication in linux

Hi guys,

can you recommend some articles/guides that can help me set this up:

- i have 10 rhel 7.3 servers
- i have 10 users who need to access all these 10 servers and su into a main app account
- rather than created a user in each one and dealing with passwords per server, I was thinking of creating 2 of the these servers (one primary and the other secondary) with a very light central user authentication service.

- all i need is to:
-- able to login to any of the 10 with the same credentials
-- mount the user's home directory in /home/nfs/<username>

thank you in advance.

A system doing exactly this is NIS. Formely called YP. This is ONE documentation page: But there are many more if you google for "NIS howto".

It is very simple, does the job and is able to mount a home directory. It was designed for that. You have to make sure that users across all machines have the same uid:gid for a username:groupname.

The other option is LDAP. But IMHO more complicated. I never used it.

IAR? Almost as much fun as a 'best easy distro' DDGoo
Any other factors (like M$evil AD)? Internet-reachable -> Security?

Let us know what eventually works out (why&how well)

p.s. @sundialsvcs: LDAP opinions? Oh, my LQsearch-kungfu
