Hi johnson,

why not? I think secure management is required in business enviroment.

It could replace the certificates in EAP Controller, but not EAP itself. You could also send email to the TPLINK Support for help. http://ticket.tp-link.com/index.php?/Tickets/Submit

Can we please get to change the certificate for the EAP Controller. It is a standard business requirement

It could change the certificate for the EAP Controller.

It is possible to change the certificate on the EAP Controller, just not easy. Generate your own key and CSR, get a valid/publicly-recognized cert, compile the key and cert into a PKCS#12 file with a "friendly name" (-name parameter when using openssl) of "eap", import the PKCS#12 file into a Java keystore file named "eap.keystore" with password "tplink", then back up and replace the eap.keystore file within "EAP Controller\keystore" with the new one you've made.

EDIT: You can find more detailed instructions here

It's really ridiculous that we have to jump through hoops to install a proper SSL certificate for a business-grade solution like EAP. Completely unacceptable in my opinion...
