Install IIS certificate on Citrix Netscaler 10.1

In our test environment I recently used an existing SSL Wildcard certificate for making the Netscaler available external, to accomplish this I needed to export the certificate from a IIS server and import the certificate into the Netscaler. When using StoreFront 2.0 which also advises you to use a SSL certificate you also need this certificate imported into the Netscaler.

Exporting the Certificates

To use the exported files we need to export the Certificate two times, one time with the private key and one time without.

1. Right click the certificate and select “All Tasks” then select “Export“. Follow the wizard and choose option ” Yes, export the private key” and continue the wizard. When you don’t get the option to export the private key, the issue a new certificate with the private key export option.

 2. When you received the option to export the private key, you now should receive the PKCS #12 (.PFX) options, uncheck all the options, click “Next” and choose a password and filename and export the Certificate.  Choose a filename that’s looks like the certificate name, because the netscaler will store the files with the names you choose. When using something like “certificate.pfx” this could get confusing in time.

 After we exported the certificate for the first time we now need to export it again.

4. Right click the certificate and select “All Tasks” then select “Export“. Follow the wizard and choose option “No, do not export the private key” and continue the wizard.
