ident - nnrpd ident resolver

       This program attempts to resolve usernames for nnrpd by using the ident protocol to query the remote
       host.  It contacts the remote host using either IPv4 or IPv6 depending on which protocol was used for the
       incoming NNTP connection.

       The  following  readers.conf(5)  fragment  tells  nnrpd  to  trust ident information for hosts on a local
       network, but to replace the domain returned from the ident query:

           auth LAN {
               hosts: "192.168/16"
               res: "ident -t"
               default-domain: "internal.example.com"
           }

           access LAN {
               users: "*@internal.example.com"
               newsgroups: example.*
           }

       Access is granted to the example.* groups for all users on the local network whose  machines  respond  to
       ident queries.

-pport
           If  this  option  is  given,  attempt  to contact identd on the specified remote port (which can be a
           numeric or symbolic specification).  Non-numeric values will be  looked  up  using  getservbyname(3).
           The default value is the result of "getservbyname("ident")" if available, or port 113 otherwise.

       -t  If this option is given, the identity returned will never have a domain part.  That is, if the remote
           server  returns  a result containing an "@" character, ident truncates the response at the "@".  This
           is useful to allow the default-domain parameter in readers.conf to override the  domain  supplied  by
           the remote host (particularly if the supplied domain part is an unqualified local machine name rather
           than a full domain name).
