Remarks

Every EAP authenticator method DLL must have public implementations of the following APIs on it.

These APIs are called on an EAP authenticator method when an authenticator (server) EAPHost receives a specific corresponding remote procedure call from a peer (client) EAP method. Note that a complete one-to-one correspondence does not exist between EAP peer methods and EAP authenticator methods; the specific EAP authenticator method API calls must be made based on the requirements of your implementation of the EAP authenticator method API calls.

Requirements

Requirement Value
Minimum supported client Windows Vista [desktop apps only]
Minimum supported server Windows Server 2008 [desktop apps only]
Header eapmethodauthenticatorapis.h
