  58     <p>This directive enables <a href="http://www.ietf.org/rfc/rfc1413.txt">RFC 1413</a>-compliant logging of the remote user name for each
  59     connection, where the client machine runs identd or something similar.
  60     This information is logged in the access log using the <code>%...l</code>

  67
  68     <p>Note that this can cause serious latency problems accessing
  69     your server since every request requires one of these lookups
  70     to be performed. When firewalls or proxy servers are involved,
  71     each lookup might possibly fail and add a latency duration as
  72     defined by the <code class="directive"><a href="#identitychecktimeout">IdentityCheckTimeout</a></code> directive to each hit. So in
  73     general this is not very useful on public servers accessible from
  74     the Internet.</p>

  87     <p>This directive specifies the timeout duration of an ident
  88     request. The default value of 30 seconds is recommended by <a href="http://www.ietf.org/rfc/rfc1413.txt">RFC 1413</a>, mainly because
  89     of possible network latency. However, you may want to adjust the
  90     timeout value according to your local network speed.</p>
