irc server make ident connections to clients.
squid can use ident for authorization.
sendmail sometimes uses ident.
maybe you want to read rfc1413.
i'd turn auth off for security reasons if your box has a direct
connection to internet.
from rfc1413:
An Identification server may reveal information about users,
entities, objects or processes which might normally be considered
private. An Identification server provides service which is a rough
analog of the CallerID services provided by some phone companies and
many of the same privacy considerations and arguments that apply to
the CallerID service apply to Identification. If you wouldn't run a
"finger" server due to privacy considerations you may not want to run
this protocol.
