Sample text

Because the type of authentication method, the EAP-Method, is variable, the Access Challenge will propose a method. This will be the preferred method available to the Authentication Server. If this method is acceptable to the Supplicant, it will respond appropriately by echoing the code for the proposed method. If it cannot support the proposed method, it will respond with a NAK and propose an alternative method. EAP has two NAK codes and it is the “Expanded NAK”—Type 254—that is used to carry this information according to the latest specs.

It defines how communication will occur, how lost packets will be handled, how fragmentation will occur, etc. The concept is that documents such as RFC 2716 (EAP-TLS) will continue to describe the logical authentication process while RFC 3579 describes the lower level physical processes that must be supported. 1X framework. 1X Remote Authentication Dial In User Service (RADIUS) Usage Guidelines. It is heavily concerned with the use of RADIUS attributes and how those attributes can be used to modify the behavior of the Authenticator when a successful authentication has been accomplished.

1X. At the time of this writing, well over 200 attributes have been defined. A subset of the attributes defined in this document can be passed back to the Authenticator if the authentication process is successful. These attributes will be used, then, to modify the actual connection established with the Supplicant. There are a number of additional RFCs that discuss aspects of RADIUS in more detail, notably RFC 2866 through RFC 2869. These are supplementary and clarify behavior. 1X, but is useful and will be discussed in later chapters.
