	#  on every request.  It may also allow TCP connections to the KDC to be
	#  cached if that is supported by the version of libkrb5 used.

	#  that it was thread safe at compile time.

		# is requested, the request will NOT get a connection.

		# idle timeout (in seconds).  A context which is
		# unused for this length of time will be freed.

		# NOTE: All configuration settings are enforced.  If a
		# context is closed because of "idle_timeout",
		# "uses", or "lifetime", then the total number of
		# contexts MAY fall below "min".  When that
		# happens, it will create a new context.  It will
		# also log a WARNING message.
		#
		# The solution is to either lower the "min" contexts,
		# or increase lifetime/idle_timeout.
