Can I use Let's Encrypt service for providing SSL certificates for my ZoneDirector?

[felix_oxley]

Has any one managed to use the free SSL provided Let's Encrypt to provide an SSL certificate for their ZoneDirector?

Thanks

Prepare 3 key file from  https://www.sslforfree.com/

1.ca_bundle.crt
2.certificate.crt
3. private.key

Go to Configure ,  Certificate 
Go to Add a trusted CA and import "ca_bundle.crt".
Go to Import Signed Certificate and import "certificate.crt".
if certificate.crt is fine, you will be asked to import the "private.key" and reboot.

If you are using 2 ZoneDirector for HA, then you need to do it in both sides.

Problem is that you have to make and install new certificate every 3 month, as certificate expiration is 90 days -- so it doesn't make much sense for me...
Easier to pay once a 3 years for certificate and forget about it until next time. 
Hope it helps
