WLC 4400: EAP-TLS

Question

Good day!
I tried to set up the EAP-TLS according to
- http://cciew.wordpress.com/2010/06/10/eap-tls-on-the-wlc/
- http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a0080a77592.shtml
- Jeremy video about EAP-TLS
The main question is about certificates.
Tell me if I am wrong -  There are two types of certificates that we need to upload to the WLC:
1) Device certificate - this is quite clear, OpenSSL, Certificate Request and e.t.c.
2) CA Root certificate - if there is only one CA Root than clear, but if we have the following chain
Root CA -> Intermediate CA -> WLC
a) Do we need to upload the whole chain "Root CA -> Intermediate CA" to the WLC ?
b) If yes, what format is it going to be? maybe smth like this
------BEGIN CERTIFICATE------
*Intermediate CA cert *
------END CERTIFICATE--------
------BEGIN CERTIFICATE------
*Root CA cert *
------END CERTIFICATE------

Nicolas, thank you for your reply!
1)
I've already seen the article, but now notice some interesting fact:
"Note: Chained certificates are supported for web authentication only; they are not supported for the management certificate."
Regarding this note, do we need to bundle any certificates for EAP-TLS scheme?
2)
On the WLC we have an opportunity to download two types of Certificates:
- Vendor Device Certificate - it is made of CSR request and then uploaded to the WLC in .pem format
- Vendor CA Certificate - this is more interesting:
  Yesterday I bundled Root and Intermediate CA Certificates in one .pem file, then uploaded it to the WLC as "Vendor CA Certificate" - the result was suсcessful! During the EAP-TLS auth process SSL Handshake completed sucessfully and I connected to my EAP WLAN!
In the controller Client Properties I saw the EAP TLS>
Everything seems to be ok, strange...
May be, the chain of Root and Intermediate CA Certificates is the redundant information, but the scheme seems to be working!
