Yeah, you've commented out connect_uri! Bad user, bad!

I'll push a fix.

You can just change:

	if (!*inst->connect_uri) {
		ERROR("rlm_rest (%s): Skipping pre-connect, connect_uri not specified", inst->xlat_name);
		return candle;
	}

in rest.c:
	if (!inst->connect_uri) {
		ERROR("rlm_rest (%s): Skipping pre-connect, connect_uri not specified", inst->xlat_name);
		return candle;
	}

Or as a work around, just set the connect URI to any URL on the server you're using,
that's the recommended configuration anyway, as it means there's no add latency 
establishing the TCP connection the first time a handle is used to service a request.

Thanks for the bug report.

Note: Before 3.0.3 (unreleased) rlm_rest is marked as an unstable module.

It was the large bit chunk of C code I wrote, and although the code organisation and general style
is ok, corner cases aren't always dealt with gracefully. 

When it was written, it involved changes to the FreeRADIUS core API to support new features, 
and unfortunately that API changed considerably between the time the module was written 
and FreeRADIUS 3.0.0 being released. That's part of the reason why there have been quite a few
issues with it.
