I'm interested in using the auth_ephemeral module to authenticate registrations with the help of an external web service.

But I'm reading and reading the documentation and I'm clearly missing something.

The document starts by describing how "the web service" should work.  I understand fully that I must implement this web service.

But nowhere in the documentation with auth_ephemeral do you tell the module the URL where the service is found.

Whilst the Makefile includes libcurl when static linking is used, there are no calls to the curl library in the auth_ephemeral module, or to socket() or connect().

So I don't see that this module can act as a client to the documented web service?

What am I failing to understand?

Thanks,

Steve
