This article describes how to replace the certificate on the App Orchestration (AO) configuration server.

Background

App Orchestration server requires a certificate for secure communication between:

• AO Management Console and AO configuration server
• AO agent and AO configuration server

Occasionally, the administrator might need to change the certificate used by the AO configuration server:

• Switch the self-sign certificate to a more robust certificate from enterprise PKI or third party commercial certificate authority when environment is ready for production usage.
• Replace the certificate that will expire soon.

Note: Changing the certificate binding through the IIS Manager on the AO configuration server will render the AO configuration server to no longer be able to communicate with the AO agent. AO agent will display “401 Unauthorized Error” in the event viewer on the machine where the AO agent is installed.

Instructions

Complete the following steps to change the certificate used for AO configuration server:

1. Open the certificate from Certificate snap-in through the MMC console to get thumbprint of the new certificate from certificate application.

2. Run the following netsh command in the command line to get a snapshot of the exist cert configuration:

   netsh http show sslcert

3. Note the application ID (this will be used later when the new certificate is added).

4. Run the following netsh command to delete the existing certificate:

   netsh http delete sslcert ipport=0.0.0.0:443

5. Run the following command to add the new cert to match to the right application id and enable the client certificate negotiation:

   netsh http add sslcert ipport=0.0.0.0:443 certhash = [your new cert thumprint] appid = {your application id in your system, need to include the braces at the start and end} clientcertnegotiation=enable

6. If the preceding command does not work properly, try the following steps:
   1. Type netsh http.

   2. Type the following command in the Netsh http prompt:

      add sslcert ipport=0.0.0.0:443 certhash= [your new cert thumprint] appid= {your application id in your system, need to include the braces at the start and end} clientcertnegotiation=enable
7. Reboot the AO configuration server or stop and start IIS and all Citrix services.

8. Check the AO console after a while. All the delivery sites and StoreFront group health should return to normal (no more yellow or red health indication about issue with the agent).
