There is oidentd:
Description: Replacement ident daemon
An ident (rfc1413) daemon for Linux. Oidentd supports most features
of pidentd as well as a number of features absent in pidentd. Most
notably, oidentd allows users, given the proper permission, to specify
the identd response that the server will output when a successful
lookup is completed. Oidentd also allows for pseudo-random strings
(either a prefix, such as "user," followed by a number between 0 and
99999, or 10 pseudo-random characters of the set 0-9A-Za-z) to be
returned upon the completion of a successful lookup instead of a
username or a UID.
Oidentd now supports IP masqueraded connections, including netfilter.
