When importing a new certificate, after you generate a CSR, the box is blank.
This is a known issue in the 10.7.4 release.
Release : 10.7.4-13
This issue is resolved by applying patch 10.7.4-285 as follows:
smg [10.7.4-13]> patch list ... sms-appliance-patch.x86_64 10.7.4-285 symrepo_smg_patches
smg [10.7.4-13]> patch -p 10.7.4-285 install
If the patch cannot be immediately installed, a workaround is to generate the certificate signing request (CSR) on another system (either Windows or Linux) and have the certificate signed by your CA. Once you have the signed certificate, you can import the certificate into Messaging Gateway (SMG) by following the instructions in the document:
This document explains how to import a CA certificate without generating a CSR on SMG, by combining the private key (generated when you generated the CSR) and the CA signed certificate in a single file prior to importing into SMG.
(NOTE: There are two sections to the document, one for private keys with a passphrase and one for private keys without a passphrase. Depending on your procedure to generate the CSR, you may or may not have to remove the passphrase.)
