"Untrusted certificate encountered while connecting to iPrint server"

Unable to manage iPrint objects through iManager
Error trying to trust the certificate after being prompted with:  "Untrusted certificate encountered while connecting to iPrint server."
               Error:  Certificate Manager Failure
               [Root exception: java.io.IOException: Keystore was tampered with, or password was incorrect] Unable to add certificate to trusted certificate store

Delete the cached files from  /var/opt/novell/tomcat5/webapps/nps/portal/modules/iPrintX/certstore/*.*
The deleted files will be recreated the next time the user is prompted to accept and/or allow a certificate when managing an iPrint object using iManager. 

Possible cause:  Corruption or incorrect information

Note:  After removing the files from the certstore directory, one reported scenario showed a follow-up error of "Internal Error  A page has performed an illegal action" when attempting to manage the Print Manager object.  In this scenario, the follow-up error was resolved by re-installing iManager, then restarting the server.   It is speculated that an iManager re-install and server restart was not necessary, but maybe a Tomcat restart would have been sufficient. (rcnovell-tomcat5 restart)

If a Tomcat restart doesn't resolve the second error, try restarting the server.   If the server restart doesn't resolve it, re-install iManager and restart the server.
