64 <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
65 connection, where the client machine runs identd or something similar.
66 This information is logged in the access log using the <code>%...l</code>
67 <a href="mod_log_config.html#formats">format string</a>.</p>
70 The information should not be trusted in any way except for
71 rudimentary usage tracking.
74 <p>Note that this can cause serious latency problems accessing
75 your server since every request requires one of these lookups
76 to be performed. When firewalls or proxy servers are involved,
77 each lookup might possibly fail and add a latency duration as
78 defined by the <code class="directive"><a href="#identitychecktimeout">IdentityCheckTimeout</a></code> directive to each hit. So in
79 general this is not very useful on public servers accessible from

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