zmcertmgr createcsr creates invalid CSR

[ChaosFreak]

Hi, I've been trying to create a CSR to generate a server certificate and have been unsuccessful so far. Each time I upload the CSR to my hosting provider "The Planet" the response comes back "Invalid CSR." My hosting provider gets their "StarterSSL" certificates from FreeSSL.com.

I have tried to generating three different CSR's using various options below:

zmcertmgr createcsr comm -new -subject "/C=US/ST=MA/L=Falmouth/O=McLane Research Labs/OU=IT Department/CN=www.mclaneengineering.com" -subjectAltNames ""

zmcertmgr createcsr comm -new -subject "/C=US/ST=MA/L=Falmouth/O=McLane Research Labs/OU=IT Department/CN=www.mclaneengineering.com" -subjectAltNames "mclaneengineering.com,mail.mclaneengineering.com"

zmcertmgr createcsr comm -new -subject "/C=US/ST=MA/L=Falmouth/O=McLane Research Labs/OU=IT Department/CN=www.mclaneengineering.com" -subjectAltNames "mclaneengineering.com"

The zmcertmgr command seems very tempermental...it fails unless you include -subjectAltNames. Is there something special about Zimbra that you have to generate your CSR with this command, or can I just use openSSL to generate my CSR?

-subject is not needed, your input between double quotes is the subject.
