 # phase2: Phase2 (inner authentication with TLS tunnel) parameters
 #	(string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
 #	"autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS)
+#
+# TLS-based methods can use the following parameters to control TLS behavior
+# (these are normally in the phase1 parameter, but can be used also in the
+# phase2 parameter when EAP-TLS is used within the inner tunnel):
+# tls_allow_md5=1 - allow MD5-based certificate signatures (depending on the
+#	TLS library, these may be disabled by default to enforce stronger
+#	security)
+# tls_disable_time_checks=1 - ignore certificate validity time (this requests
+#	the TLS library to accept certificates even if they are not currently
+#	valid, i.e., have expired or have not yet become valid; this should be
+#	used only for testing purposes)
+# tls_disable_session_ticket=1 - disable TLS Session Ticket extension
+# tls_disable_session_ticket=0 - allow TLS Session Ticket extension to be used
+#	Note: If not set, this is automatically set to 1 for EAP-TLS/PEAP/TTLS
+#	as a workaround for broken authentication server implementations unless
+#	EAP workarounds are disabled with eap_workarounds=0.
+#	For EAP-FAST, this must be set to 0 (or left unconfigured for the
+#	default value to be used automatically).

 # Following certificate/private key fields are used in inner Phase2
 # authentication when using EAP-TTLS or EAP-PEAP.
 # ca_cert2: File path to CA certificate file. This file can have one or more
