Preexisting Certifcate Installation for Zimbra 6.0

Revision as of 23:39, 4 March 2010 by Yaaar (talk | contribs)

Zimbra makes it extremely easy to install either a self-signed certificate or a commercial certificate specific to the zimbra server. If, on the other hand, you want to install a certificate you created somewhere else (such as a wildcard certificate for your domain) the procedure is a bit more involved.

Become root, make a directory to work in and bring the files over. There are lots of ways to do this; I used scp:

mkdir /root/certs
cd /root/certs
scp .
scp .
scp .

Now you need to rename the files to what Zimbra expects:

mv commercial.crt
mv commercial.key
mv ca_bundle.crt commercial_ca.crt

Next you put the key file in two places where Zimbra expects it:

cp commercial.key /opt/zimbra/ssl/zimbra
mv commercial.key /opt/zimbra/ssl/zimbra/commercial

Then you use Zimbra's fancy certificate importer tools. Note the last command spans two lines...either use the backslash as indicated, or paste both lines into one command, leaving the backslash out. Also, the password really is "changeit" ...don't be like me and screw around forever trying to figure out what to change it to.

/opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial.key commercial.crt commercial_ca.crt
/opt/zimbra/bin/zmcertmgr deploycrt comm commercial.crt commercial_ca.crt
/opt/zimbra/java/bin/keytool -import -alias root -keystore\
/opt/zimbra/java/jre/lib/security/cacerts -storepass changeit -file /opt/zimbra/conf/ca/commercial_ca.pem

Then you restart Zimbra:

/etc/init.d/zimbra restart
