OpenLDAP slapd, like may other daemons, relies on timeouts being a
reasonably short (a few hours) to deal with dead streams.  Dead
streams occur for a wide variety of reasons and erver applications
need an effective mechanisms to deal with them.  Changing the
timeout to a week would render the SO_KEEPALIVE mechanism
ineffective.

Personally, I advocate using sysctl (in rc files) to set the
default to on and leaving the kernel alone.
