By popular demand, ident_stream now takes arguments. Ex:

Browse Source 
# This enables the old, fake ident service.
auth    stream  tcp     nowait  root    internal
# This enables the new, real ident service.
auth	stream	tcp	nowait	root	internal	auth -r
# This enables ~/.fakeid support, too.
auth	stream	tcp	nowait	root	internal	auth -r -f
