NOTES
Setting a high ttl value allows objects to stay persistent in caches for a longer period of time and can
improve performance. However, when an object changes, in the worst case, the number of seconds in this
attribute must pass before that change is visible to all clients. Setting a
ttl value of 0 means that the
object should not be cached at all.
A high
ttl value is a week, a low value is less than a minute. Password entries should have
ttl values of
about 12 hours (easily allows one password change per day), entries in the RPC table can have
ttl values
of several weeks (this information is effectively unchanging).
Only directory and group objects are cached in this implementation.
