request authorization with grpc (failure status code)

[bmacphee]

Yes, I was trying various combinations of the following, with no success.

location @grpc_auth_fail {
       add_trailer grpc-status 16 always;
       add_header grpc-status 16 always;
       add_trailer grpc-message Unauthorized always;
       add_header grpc-message Unauthorized always;
       return 401;
       #return 200;
}


The choice of 16 for the status was based on this documentation (which is
similar to the one you linked):
https://grpc.github.io/grpc/core/md_doc_statuscodes.html
