48 <p>This directive enables <a href="http://www.ietf.org/rfc/rfc1413.txt"
49 >RFC 1413</a>-compliant logging of the remote user name for each
50 connection, where the client machine runs identd or something similar.
51 This information is logged in the access log using the <code>%...l</code>
52 <a href="mod_log_config.html#formats">format string</a>.</p>
55 The information should not be trusted in any way except for
56 rudimentary usage tracking.
59 <p>Note that this can cause serious latency problems accessing
60 your server since every request requires one of these lookups
61 to be performed. When firewalls or proxy servers are involved,
62 each lookup might possibly fail and add a latency duration as
63 defined by the <directive module="mod_ident"
64 >IdentityCheckTimeout</directive> directive to each hit. So in
65 general this is not very useful on public servers accessible from

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