As per this issue:

https://github.com/zeromq/czmq/issues/385

I'm using the ironhouse2 example. If I comment out the line where it 
saves the client's public key for the server, the example still works. I expect the server should refuse the connection since the key isn't 
installed. This is with 2.0.3. Same thing with changing the IP address in zauth_allow().


I tried running the (unmodified) example with latest libzmq and czmq git but it was giving this error:

/tmp/czmq/examples/security> ./ironhouse
ironhouse: zsockopt.c:397: zsocket_set_curve_secretkey_bin: Assertion `rc == 0 || zmq_errno () == (156384712 + 53)' failed.
