EAP-chaining with internal ID stores

Hello Friends!

Today I tryed to implement EAP-chaining, but without certificate and AD integration.

I didn`t find any information about it. All existig info regards of AD integration, and machine cert validation.

Is it possible to do machine authentication using Internal Devices same way that we do User auth with Internal User store?

As result a have this

SelectedAuthenticationIdentityStores	Internal Users
SelectedAuthenticationIdentityStores	Internal Endpoints
SelectedAuthenticationIdentityStores	All_AD_Join_Points
SelectedAuthenticationIdentityStores	Guest Users

EapChainingResult

User succeeded and machine failed

	12219	Selected identity type 'Machine'
	12125	EAP-FAST inner method started
	11521	Prepared EAP-Request/Identity for inner EAP method
	12105	Prepared EAP-Request with another EAP-FAST challenge
	11006	Returned RADIUS Access-Challenge
	11001	Received RADIUS Access-Request
	11018	RADIUS is re-using an existing session
	12104	Extracted EAP-Response containing EAP-FAST challenge-response
	12213	Identity type provided by client is not equal to requested type
	12216	Identity type provided by client was already used for authentication
	12967	Sent EAP Intermediate Result TLV indicating failure
	12105	Prepared EAP-Request with another EAP-FAST challenge
	11006	Returned RADIUS Access-Challenge
	11001	Received RADIUS Access-Request
	11018	RADIUS is re-using an existing session
	12104	Extracted EAP-Response containing EAP-FAST challenge-response
	24715	ISE has not confirmed locally previous successful machine authentication for user in Active Directory

A don`t understand what I`m doing wrong.

Thanks in advance,

Tom

This is not a supported setup as EAP-Chaining is for Windows environment ATM. Remember that machine authentication requires domain joined machine to function properly, which is not possible with ISE internal database. You may be able to fake machine authentication using machine certificate to bypass domain join requirement and make it work, but still not an orthodox setup.

Can you provide why you are looking for such setup?

Thanks for your reference.

Actually there is no real reason to do this, I was only doing this because of temporary disabled CA role in our DC.

Again, thanks, It looks like I didn`t complete realize how chaining works(and generated this strange topic:)).
