+#
+# This option is used with timestamp:
+#
+# usercombo -> "timestamp:userid"
+# turn user -> usercombo
+# turn password -> base64(hmac(secret key, usercombo))
+#
+# This allows TURN credentials to be accounted for a specific user id.
+# If you don't have a suitable id, the timestamp alone can be used.
+# This option is just turning on secret-based authentication.
+# The actual value of the secret is defined either by option static-auth-secret,
+# or can be found in the turn_secret table in the database (see below).

+# You can use only one of the to auth mechanisms in the same time because,
