ACS 5.3 EAP-TLS configuration issue

Dear all,

We are trying to configure EAP-TLS for 802.1x user authentication (still working with ACS 4.1 ) with Version : 5.3.0.40.5 ...

I reached the point where i receiveed the following error:

"EAP-TLS failed SSL/TLS handshake because of an unknown CA in the client certificates chain"

So I have 2 questions:

- is there a guideline somewhere as i should have forgotten something ?

- Is there a way to check the certificates chain or to have more logs somewhere in the ACS ?

regards,

vincent.

You will have to import the root and intermediate certificates that are presented from the clients end over to ACS.

Here is a documentation on how to do this - http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_system/5.3/user/guide/users_id_stores.html#wp1158666

Make sure the Trust for Client with EAP-TLS is checked.

thanks,
