Information About Local EAP
Local Extensible Authentication Protocol (EAP) feature refers to the controller that acts as autheticator and authentication server. Local EAP allows 802.1x authentication on WPA Enterprise wireless clients without the use of any RADIUS server. The Local EAP refers to the EAP authentication server activity and not necessarily tied to the user credentials validation (for example) that can be delegated to an external LDAP database.
Local EAP is designed to allow administrators to use Enterprise-grade 802.1x authentication for a limited number of users in situations and branches where an external dedicated RADIUS server may not be available. It can also work as an emergency backup in case the RADIUS server is not available.
You can implement Local EAP either with users local to the controller or use an external LDAP database to store the user credentials.
