Hi.
We use community version 6.
When i try to install commercial certificate into Zimbra i get errors:

./zmcertmgr deploycrt comm /tmp/server.crt /tmp/ca_bundle.crt
** Verifying /tmp/server.crt against /opt/zimbra/ssl/zimbra/commercial/commercial.key
Certificate (/tmp/server.crt) and private key (/opt/zimbra/ssl/zimbra/commercial/commercial.key) match.

I've used this article to install cert: Installing a RapidSSL Commercial Certificate - Zimbra :: Wiki

Someone has similar problem?
Thx.
