man slapd-meta(5)
       network-timeout <time>
              Sets the network timeout value after which poll(2)/select(2)
              following a connect(2) returns in case of no activity.  The
              value is in seconds, and it can be specified as for
              idle-timeout. If set before any target specification, it affects
              all targets, unless overridden by any per-target directive.
