+# This test requires external setup and thus is skipped unless
+# TEST_SSH_HOSTBASED_AUTH and SUDO are set to "yes".
+# Since ssh-keysign has key paths hard coded, unlike the other tests it
+# needs to use the real host keys. It requires:
+# - ssh-keysign must be installed and setuid.
+# - "EnableSSHKeysign yes" must be in the system ssh_config.
+# - the system's own real FQDN the system-wide shosts.equiv.
+# - the system's real public key fingerprints must be in global ssh_known_hosts.
