Thanks Robert,
Each teacher and each student have their own accounts and home directories
so they all log on anywhere in the school. The teacher "servers" (i.e.
machines) will be located by the teachers work desks mainly so they can
keep a close eye on them.
I'm using webmin as an administrative GUI but can and do sometimes do
things from the CL.
The current install is EdUbuntu 12.04 w/o LDAP.
The reason I was thinking of making a new install is safety because the
current machine is the production unit. If I could get the main
authentication and home directory server set up, add two more
teacher/server cluster units then I can move the authentication passwords,
user accounts, home directories and the network to the new cluster control
server. After that is set up I would definitely want the current production
unit to be added to the cluster but probably only as an app server right? I
mean, it is the strongest machine we have and could handle most of the apps
by itself whereas the authentication/ cluster control server has a lighter
load and doesn't need to be as powerful correct?
