Authenticate SSH user in a H3C Switch using FreeRadius + OpenLDAP

10 May 2017

      I have a problem that I not able to fix it. I am trying to authenticate a
SSH user in a H3C switch. This switch is configured to authenticate the
user in a Radius server wich is using openldap to store the user's name and
password. Everytime I try to authenticate, I see a message in the
radius.log saying that "[eap] No EAP-Message, not doing EAP". I tryed do
use PAP, but I got "[pap] WARNING! No "known good" password found for the
user.  Authentication may fail because of this." Dont't know what to do
anymore. I don't know how to (and if I have to) force the switch to use EAP
packetes.
