Strange that this would affect your administration console. You could try manually replacing the key pair in the device manager's keystore (/var/opt/novell/novlwww/devman.keystore). It probably goes without saying, but you will really want to back up the current keystore before doing anything.

Replace this with your own certificate pair. Relevant commands can be found at http://www.sslshopper.com/article-mo...-commands.html
/opt/novell/java/jre/bin/keytool -list -v -keystore devman.keystore
Once you do this, restart the administration console and try to access it again. As soon as you get in, update the AC key pair through the administration console interface. Good luck!
