+# RADIUS over TLS (radsec)
+#
+# When a new client connects, the various TLS parameters for the
+# connection are available as dynamic expansions, e.g.
+#
+# %{listen:TLS-Client-Cert-Common-Name}
+#
+# Along with other TLS-Client-Cert-... attributes.
+# These expansions will only exist if the relevant fields
+# are in the client certificate. Read the debug output to see
+# which fields are available. Look for output like the following:
+#
+# (0) TLS - Creating attributes from certificate OIDs
+# (0) TLS-Client-Cert-Subject-Alt-Name-Dns := "one.example.org"
+# (0) TLS-Client-Cert-Subject-Alt-Name-Dns := "two.example.org"
+# ...
+#
+# It is also possible to distinguish between connections which have
+# TLS enables, and ones which do not. The expansion:
+#
+# %{listen:tls}
+#
+# Will return "yes" if the connection has TLS enabled. It will
+# return "no" if TLS is not enabled for a particular listen section.
+#
+# A number of TLS-Client-Cert-.. attributes holds X509v3 extensions
+# data, attributes named the way OpenSSL names them. It is possible
+# to extract data for an extension not known to OpenSSL by defining
+# a custom string attribute which contains extension OID in it's
+# name after 'TLS-Client-Cert-' prefix. E.g.:
+#
+# ATTRIBUTE TLS-Client-Cert-1.3.6.1.4.1.311.21.7 3002 string
+#
+# which will yield something simmilar to:
+#
+# (0) eap_tls: TLS - Creating attributes from certificate OIDs
+# (0) eap_tls: TLS-Client-Cert-1.3.6.1.4.1.311.21.7 += "0x302e06"
