it depends on how often you are doing the searches.
I have one (vendor-written) application that occasionally decides to do a half \
million queries over 36 hours. It does a separate bind and unbind for each, and as \
the LDAP system administrator, I really wish it would bind once then do the queries.
I also have applications that make connections and do not use them for hours on end. \
They tie up resources, and the dead-connection monitor on our load balancer and on \
the LDAP server tend to kill the connections when not in use that long.
If it's going less often than between every 15-60s, then I'd set up and tear down for \
every batch of searches...

Hello Guys,
I wrote a script that runs as a system process. If I do constant searches on the LDAP \
server how often should I bind and unbind from the server.
Should I do only one and maintain it. But what about if it disconnects due to \
inactivity during the night. Can I simply bind again on the same object?
Or should I bind, then search, then unbind each time?
Advice?
Thanks,
