Easy Ways To Generate Zimbra SSL Certificate

In my workplaces is a Zimbra Authorized Partners offering Zimbra Mail Server visit maintenance or remote service.

One of favorite service of PT Excellent Infotama Kreasindo is Zimbra VPS Cloud, where client can using their email server for company without Investing a Hardware and Email Administrator, because the server will be handled professionaly with us. If client have a obstacle with server, the team support will be happy for help.

And i was one of the support team for the service. Every order comes, I demanded to be faster in the setup. One of the trick, i made a simple bash script for Generate Zimbra SSL (CSR) Certificate.

Refers to Zimbra Wiki, the command for Generate CSR are :

Single Domain

/opt/zimbra/bin/zmcertmgr createcsr comm -new -subject "/C=ID/ST=Jawa Barat/L=Bekasi/O=PT Excellent Infotama Kreasindo/OU=IT/CN=mail.excellent.co.id" -subjectAltNames mail.excellent.co.id

Multi Domain (UCC)

/opt/zimbra/bin/zmcertmgr createcsr comm -new -subject "/C=ID/ST=Jawa Barat/L=Bekasi/O=PT Excellent Infotama Kreasindo/OU=IT/CN=mail.excellent.co.id" -subjectAltNames mail.excellent.co.id,mail.dhenandi.web.id,www.fiqmanaufal.com

Wildcard Domain

/opt/zimbra/bin/zmcertmgr createcsr comm -new -subject "/C=ID/ST=Jawa Barat/L=Lokasi/O=PT Excellent Infotama Kreasindo/OU=IT/CN=*.dhenandi.web.id"

With the command, i had to change one by one for the Certificate identity by directing mouse or keyboard to the each of field, so lazy 😀 At least, with my simple script, i can fill the field with Just Hit the “Enter” key :-P.
