Hi Rachana,

Thanks for the reply and the pointers.  FYI, I read the documentation
before posting but obviously I wasn't able to find the relevant
material.  I think this material should be in the Admin Guide, not the
Developer's Guide.  Do you agree?  If so, I'll create a bug.

So if I'm understanding the docs correctly, a lower-level config
completely overrides a higher-level config.  In other words, only one
authz chain is invoked (in 4.0, at least).

The 4.1+ documentation is much clearer on this issue, thanks, but what
happens at any step if the authz chain returns indeterminate?  Also,
where can I find more info on configuring administrative policy?  I
don't see any reference to that in the Admin Guide or the Developer's
Guide.

Thanks,
Tom
