4.4 Replacing an External Server Certificate with a New External Server Certificate Issued by a Different Certificate Authority

If you want to change your zone certificate authority, take a reliable backup of the following on all Primary Servers in the Management Zone:
- Content-Repo Directory: The content-repo directory is located by default in the ZENworks_installation_directory\work directory on Windows and in the /var/opt/novell/zenworks/ on Linux.
  
  Ensure that the images directory located within the content-repo directory has been successfully backed up.
- Embedded Database: For detailed information on how to back up the embedded database, see in Backing Up the Embedded Sybase SQL Anywhere Database in the ZENworks 11 SP3 Database Management Reference.
- ZENworks Server: For detailed information on how to back up the ZENworks Server, see Section 1.1, Backing Up a ZENworks Server.
Create a server certificate by using the new certificate authority for each Primary Server in the zone by providing the fully qualified DNS (FQDN) of the Primary Server as the subject.

For more information on how to create a CSR, for Windows, see Creating an External Certificate and for Linux, see Creating an External Certificate.
At the console prompt of a Primary Server, run the following command:

zman sacert Path_of_the_Primary_Server_in_ZENworks_Control_Center Path_of_Primary_Server_Certificate

For more information about zman, view the zman man page (man zman) on the device or see zman(1) in the ZENworks 11 SP3 Command Line Utilities Reference.

This adds the certificate of the Primary Server that you specified in the command to the ZENworks database and certificate store.

NOTE:You must run the command for each Primary Server whose certificate you want to replace.
Refresh all the devices, including the Primary Servers, in the zone.

The Primary Server certificates that were imported in Step 3 are sent to the devices as configuration data.
Import the root certificate of the new certificate authority into the trusted store on all the devices in the zone through the zac cert-info command. You can choose to execute the command in one of the following ways:
- Manually run the following command on each Primary Server and managed device in the zone:
  
  zac cert-info certificate_file_path -u zone_administrator_username -p zone_administrator_password
  
  For more information about zac, view the zac man page (man zac) on the device or see the ZENworks 11 SP3 Command Line Utilities Reference.
- Use a ZENworks bundle.
  
  For more information about bundles, see Creating Bundles in the ZENworks 11 SP3 Software Distribution Reference.
Enforce the new certificates on the zone by running the following command on any Primary Server:

novell-zenworks-configure -c SSL -Z

Follow the prompts.
Restart all the ZENworks services on all the Primary Servers in the zone by running the following command at the console prompt of each Primary Server in the zone:

novell-zenworks-configure -c Start

By default, all the services are selected. You must select Restart as the Action.
Ensure that DNS is properly configured for the Primary Servers, so that server host names get resolved. For DNS resolution requirements, see DNS Resolution in the ZENworks 11 SP3 System Requirements.

Run the following commands in the same sequence:

novell-zenworks-configure -Z -c MergeTruststore

novell-zenworks-configure -c EnableJMX

novell-zenworks-configure -c ZenProbe
Refresh all the devices, including the Primary Servers, in the zone.
(Conditional) If any device is not reachable during the refresh, you must first establish a connection with the device, then run the following command at the console prompt of each device to reestablish the trust between the device and the zone:

zac retr -u zone_administrator_username -p zone_administrator_password
Configure the Satellites with the new external certificates by entering the following command at the Satellite's prompt:

zac iac -pk private-key.der -c signed-server_certificate.der -ca signing-authority-public-certificate.der -ks keystore.jks -ksp keystore-pass-phrase -a signed-cert-alias -ks signed-cert-passphrase -u username -p password -rc

For more information about zac, view the zac man page (man zac) on the device or see the ZENworks 11 SP3 Command Line Utilities Reference.
Re-create all the default and custom deployment packages for all the Primary Servers:
- Default Deployment Packages: At the console prompt of each Primary Server in the zone, enter the following command:
  
  novell-zenworks-configure -c CreateExtractorPacks -Z
- Custom Deployment Packages: At the console prompt of each Primary Server in the zone, enter the following command:
  
  novell-zenworks- configure -c RebuildCustomPacks -Z
(Conditional) If your zone includes Intel AMT devices, unprovision and provision the devices.

For more information about unprovisioning and provisioning Intel AMT devices, see Configuring Intel AMT Devices in Enterprise Mode in the ZENworks 11 SP3 Out-of-Band Management Reference.
(Conditional) If multizone is configured with the server whose certificate has got replaced as the Publisher, then update the new certificate of this server for all its Subscribers. Perform the following to update the new certificate:
1. Log in to ZENworks Control Center (ZCC) of subscribers.
2. Navigate to Subscribe And Share > Subscriptions > <subscription_name> > Remote Server > Update Certificate.
3. Update the certificate.

NOTE:Because ZENworks and ZENworks Reporting does not use the same certificate, the ZENworks Reporting does not require any configuration changes if the ZENworks certificate is changed. However, if you want to replace the certificate of ZENworks Reporting with the new certificate, you must run ZENworks Reporting Configuration Tool.

For more information, see ZENworks Reporting Configuration Tool in the ZENworks Reporting 5 System Reference.
