Cacao MBean Server - No trusted certificate found

We are trying to set up a development environment to test a patch for Sun Portal Server 7.1.

(Yes, pretty old version. And yes, our company is pretty strict. If customer does not have a development/staging environment to test the new patch, we need to set it up in our office. Otherwise, it's a No-Go!)

Not smooth sailing... Encountered the following error:

bash-3.00# /opt/SUNWportal/bin/psconfig --config ps.xml

It must be Cacao again! I hate this "animal"! 

I suspect it's a certificate issue when I rename our Solaris OS hostname from testportal to portal.

Let's recreate the Cacao key again!

bash-3.00# cacaoadm stop

bash-3.00# cacaoadm create-keys --force

bash-3.00# cacaoadm start

Bingo! The configuration can now proceed ...
