Keith Wall commented on QPID-6018:
----------------------------------
I think the fact that SimpleAuthenticationProvider is a class (rather than an
interface) confuses the COF Factory. It seems to me we also need a attribute
that can tag such configured object as 'internal' and by default should be
excluded from the metadata service.

> SimpleAuthenticationProvider is used internally by Management mode, and
> should not be available for the user to choose. It appears on the drop down
> list of available authentication providers. If the user chooses it, he
