I'm administrating two ubuntu desktops and one debian server. There are abount ~20 active users on the desktops. A few (5-10) user accounts are added each year and about the same amount become inactive.
I would like to share the user accounts and their respective homes between the two pcs. So far, my plan was to set up some kind of nfs + kerberos (+ldap/nis?), but I think kerberos is overly complicated for this simple purpose. In addition to that, the admin changes every ~2-3 years and I fear that complicated solutions will become unmaintainable for my successors (we are no professionals...).
Is there a way to split up /etc/passwd etc. in different files, so I could store these on the server and copy them to the desktops? Or is there some PAM-module that provides a similar type of "modular" authentication ? (well, except pam_krb5).
What would be the simplest way to achieve that?
