When you manage Print Managers, driver stores, and printers that are running on a different server than the server running iManager, you might receive a certificate error, meaning that the host name or IP address of the server where you are managing the print object does not match any of the certificates on the server where iManager is running.
To find and accept the correct certificate:
Click the iPrint Certificate Manager link in the error.
Review the certificate information for accuracy.
Select the action you want to perform for this certificate.
In order to manage the print object, you must accept the certificate.
Click OK.
You might need to scroll down in order to click OK to accept the certificate.
Restart your task.
Certificates are accepted on a per-user basis.
You can remove accepted certificates by deleting the certstore folder located at: /var/opt/novell/iManager/nps/portal/modules/iPrintX/certstore. Deleting this folder removes all accepted certificates.
