Set up one or two backup NIS servers, they will sync with each other.
Then when the master server goes down, the clients hit the secondary.

NIS doesn't have to mount the home from the same machine...it just
provides the home path.

I use autofs, which usually works well. The worst problem i've had is
when the machines are under very high load and an nfs server dies, you
need to restart the automount processes on the affected clients.

LDAP seems more flaky than NIS to me...just an opinion from experience
tho.

Kerberos also works very well...the problems are the learning curve for
lusers and it's a pain to implement.
