> Project: TinkerPop 3
> Issue Type: Bug

> Errors with HTTP REST basic auth. I was able to reproduce this on tp30 and
> master. I have a pull request coming.
> 1. Built the latest tp30 branch. Copied gremlin-server-secure.yaml to
> gremlin-server-secure-rest.yaml and updated the channelizer to
> org.apache.tinkerpop.gremlin.server.channel.HttpChannelizer.
> Ran this command.

> I fixed this by moving the initialization of the authentication handler in
> HttpChannelizer from init() to configure(). It doesn't seem like a safe to
> assumption that the Authenticator interface implementation can be shared.
> 3. After that worked, the other thing I noticed is that if authorization
> fails, the curl doesn't close.
