-
well - i'm not saying that it does - i'm saying that we now have a {{write()}}
step and since it's part of the Gremlin language now I'd think we could surely
make use of it for writing results to places if we wanted it to.

Oh, I didn't realize that it can do that, I thought it can only handle graphs.
I need to play with it, but if it works as shown in your snippet, then that's
that.

[GitHub] tinkerpop issue #889: Tinkerpop 1977 - Sasl Authentication
Github user mattallenuk commented on the issue:
https://github.com/apache/tinkerpop/pull/889
@jorgebay I've modified the Sasl Authenticator so that a mechanism can now
be passed in along with any mechanism options. I've changed the Sasl Plain
Authenticator to mimic the Java handler code as discussed, however I had to do
some fudging as I couldn't get the flow to work right.
From my understanding of the Java code the
Driver/Handler/GremlinSaslAuthenticationHandler class receives a 407 from the
Gremlin Server and then sends a message containing { saslMechanism: 'PLAIN',
sasl: (A base64 encoded null byte string) }, the server then returns an initial
response and the client then sends the actual sasl authentication message... I
tried that and I was getting a message that "Authentication ID must not be
null". Having looked at the Gremlin Server code and the
Handler/SaslAuthenticationHandler class and the Auth/SimpleAuthentication class
it doesn't appear that saslMechanism token is actually parsed and the the
server expects the actual sasl message right away. So, currently, in the JS
SaslAuthenticator class I've passed the full Sasl message with the initial
SaslMechanism argument.
I hope that makes sense and if it needs changing I'm happy to do so.
