Idea for simple LTSP cluster out of the box

If I am not mistaken, ldm support multiple servers listed in its
LDM_SERVER configuration variable.  We could use this to provide a
LTSP cluster solution out of the box with a trivial change to the
current configuration.

All LTSP servers on the network are expected to be a member of the
ltsp-server netgroup in LDAP.  If this is the case, we can fill the
LDM_SERVER variable at run time with the content from this netgroup,
and LDM will then pick the first server in the list.  If we make sure
to randomize the list or order it based on load or something like
that, we would have a load balancing LTSP cluster out of the box.

I was floating this idea some years ago in

Perhaps time to make this a default feature?

Happy hacking,
Petter Reinholdtsen
