Actually a bad idea: A few years again I wrote a TCP redirector that had problems:
First, I had no timeout, so dead connections could not be detected, so I added a timeout.
Second, idle connections timed out, so I added keep-alive.
Then I was happy.

It seems LDAP connections here also live for a very long time, sometimes idle for hours...

Ulrich
