How to make one rhel5 server control passwords for several rhel5 servers.


Hello;

I am relatively new to rhel5, and I am in the process of setting up 6 rhel5 servers, and I would like to set them up where you only have to log into one(Master)server with username and password, and be able to access the others. (Single Sign-On like).


Thank you in advance for the assistance.

Hi, and welcome to LQ!

There is no mechanism I'm aware of that allows "single sign-on"
over various servers as such; what you can do is set-up an ssh
account with a complex pass-phrase on your local box, and use
passwordless authentication with ssh to log onto your machines.

Of course, that only controls your pass-phrase locally on your
workstation.


Cheers,
Tink

Would setting up an NIS Server on one, and making the rest NIS clients perform nearly the same function???

Thanks for your assistance.

No, it wouldn't. You'd just assure that you can use the same password
on all; but you'd still need to authenticate against them individually.

And on that note: NIS has pretty much been obsoleted. If you think of
directory services go LDAP.

But maybe single sign-on to you means something different from the rest
of the industry? If identical credentials is all you're after you may
want to look at quite different possible solutions:

a) use puppet to maintain the passwd, group & shadow files and push it
to all machines
b) define one of the machines to have password-less auth to the others
via ssh, and if passwd/group/shadow change use inotify or dazuko to
push them via script.
c) ....




Cheers,
Tink
