Most primitive way: copy the password & group files over from a central server. But you don't want to do that.

Better: set up an LDAP server, and authenticate users using pam_ldap, with the home directories on a NFS server. Here's a description for Debian, and one for Arch.

You can also use kerberos server with pam_krb

Be careful tho, kerberos is somewhat complicated to setup and requires clients and server to be in time sync.
But should be the most secure way.
