This isn't going to work. With such a low number of worker
connections nginx won't be able to start worker processes properly
(unless you have no listening sockets configured).

Try looking into error log, you should see something like:

2012/10/24 20:17:53 [alert] 58202#0: 1 worker_connections are not enough
2012/10/24 20:17:53 [notice] 58201#0: signal 20 (SIGCHLD) received
2012/10/24 20:17:53 [notice] 58201#0: worker process 58202 exited with code 2
2012/10/24 20:17:53 [alert] 58201#0: worker process 58202 exited with fatal code 2 and cannot be respawned

You have to set worker_processes to something reasonable.
Something like 512 as by default is usually a good choice for a
small test server.

The auth service is requested when nginx needs to authenticate a
client and to find out a backend server address to proxy the
client to.
