#  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"
