This is for the FLAP-level sign on method. This is the oldest method of sign on, used prior to AIM 3.5. This refers to the FLAP__FRAME_SIGNON authentication method for a user to authenticate to the network. This works similar to, but is not the same as, FLAP__FRAME_SIGNON sequences used to connect to BOSS and other services.

Sequence

Below is a table laying out the sequence, which is further detailed in the sections below. Keep in mind that all of the packets are FLAP packets, and thus only the data is discussed.

Origin Name Length Value Note
Host FLAP_VERSION 4 00 00 00 01 Always 0x01
Client FLAP_FRAME_SIGNON blob xx .. TLV chain containing authentication information
Host FLAP_FRAME_SIGNOFF blob xx .. TLV chain of either BOSS or error information
