OK, I suspected that the cert being used as the external CA cert was the
problem.  As I recall, there is a current bug being fixed to address
issues with Microsoft issued CA certs.  If you can use a dogtag cert as
your external CA, then you'll avoid any issues.

I don't understand what you are trying to do here.  You have created
several dogtag CA's that are subordinate to the external CA.  They are
CA's in their own right, with their own signing certificates.  Why do
they need access to the root CA?

If you want several CA's with exactly the same signing cert, then you
want clones.
