Download the Signed Client Certificate

Describes how to download a signed client certificate to the data-fabric system.

After you have installed your signed client certificate on the ESKM server, you need to download it to the data-fabric hosts running the KMIP client, that is. the data-fabric CLDB hosts. To do this:

Click Security > Certificates, and navigate to the Certificate List section.
Select the certificate where the Certificate Name matches the Common Name (CN) that you specified when creating your CSR. Then click Properties. The Certificate Information page is displayed.
Click Download to download the client certificate to your data-fabric CLDB host. In the example, since the CN for the certificate is maprkmipclient1, the signed client certificate is saved to a file named maprkmipclient1.crt in PEM format.
