EAP-TTLS auth

Hi Fernando, 

It is highly recommended that you turn off HTML capability on your e-mail
client to post comments to this list. Many people on the list have chosen to
use mail programs that aren't HTML capable and they can barely read your
message -- it shows up as HTML junk.

If you're using a mail program that is HTML capable such as Netscape or
Outlook, please turn HTML posting off. Use plain text only.

Regards, 
AG
