Zimbra

Introduction

After install letsencrypt certificate via the beautiful /opt/letsencrypt-zimbra/obtain-and-deploy-letsencrypt-cert.sh, the certificate of the admin console (accessible via port 7071) has not been updated. The keystore is located at /opt/zimbra/mailboxd/etc/keystore

zmcertmgr viewdeployedcrt all
SubjectAltName=mail.domain.tld

NOTE: possibly stale keystore: /opt/zimbra/mailboxd/etc/keystore - mailboxd: /opt/zimbra/mailboxd/etc/mailboxd.pem notBefore=Jul 31 20:31:04 2021 GMT notAfter=Oct 29 20:31:02 2021 GMT subject=CN = mail.domain.tld issuer=C = US, O = Let's Encrypt, CN = R3

Find the keystore password in zimbra configuration

zmlocalconfig -s | grep mailboxd_keystore_password

Create a pkcs12 file with the certificate, chain and the private key (as zimbra user)

openssl pkcs12 -export -name jetty -in /opt/zimbra/ssl/zimbra/commercial/commercial.crt -inkey /opt/zimbra/ssl/zimbra/commercial/commercial.key -out jetty.p12

Delete the actual certificate into keystore

keytool -delete -alias jetty -keystore keystore -storepass passwd

Import the keystore into the keystore (haha)

keytool -importkeystore -destkeystore keystore -srckeystore jetty.p12 -srcstoretype jks
zmcontrol restart
