This read-create INTEGER specifies the inner EAP authentication type (such as eapTLS, eapLEAP, eapSIM, or eapTTLS) used when tunneled/inner EAP authentication is chosen for a realm; it is set to reserved when a different authentication type applies, and the object is noted as superseded by cLHotspotEAPAuthTable. It lets an admin declare, for legacy configurations, which inner method a realm's authentication tunnel expects. For example, a realm configured for EAP-TTLS with an inner EAP-TLS exchange would have this object set to eapTLS to describe that inner method.
