We need to use logstash 1.4.2 to store documents into MongoDB version 3.0 with new SCRAM-SHA-1 authentication mechanism enabled.

No documents are written in mongodb with following configuration file:
output {
mongodb {
collection => '%{type}'
database => 'nfmdata'
uri => 'mongodb://nfmoss:nfmoss@127.0.0.1'
}
}

If we add to uri parameter the connection authentication option:
uri => 'mongodb://nfmoss:nfmoss@127.0.0.1/?authMechanism=SCRAM-SHA-1'

we have the following error:
Mongo::MongoArgumentError: Invalid value "scram-sha-1" for authmechanism: must be one of GSSAPI, MONGODB-CR, MONGODB-X509, PLAIN

It seems that mongodb output plugin has to be lined up to MongoDB Java driver version compatible with MongoDB version 3.0, that is at least 2.13.0 version.
Otherwise, authentication will fail because the server is expecting the driver to use the new SCRAM-SHA1 authentication protocol rather than the MONGODB-CR authentication protocol that it replaces.

This issue is equal to issue #2 opened 21 days ago by me, so I close this.

relates to #20 #42 and #35 - the library clearly need to be updated.
