Auth Problem when connecting to Neo4j Server (Ubuntu)

[appren...@gmail.com]

I'm trying to setup neo4j on ubuntu virtual server but having issues connecting.

curl -H "Accept: application/json; charset=UTF-8" -H "Content-Type: application/json" -X POST http://localhost:7474/db/data/cypher -d '{

>   "query" : "CREATE (n:Person { name : {name} }) RETURN n",

>   "params" : {

>     "name" : "Foo"

>   }

> }'

{

  "errors" : [ {

    "code" : "Neo.ClientError.Security.Unauthorized",

    "message" : "No authentication header supplied."

  } ]

}

if i try to change password with 'neo4j-admin set-initial-password'

i get : command failed: initial password was not set because live Neo4j-users were detected.

when i try to change the password with a rest call:

curl -H "Accept: application/json; charset=UTF-8" -H "Content-Type: application/json" -X POST http://localhost:7474/user/neo4j/newpass12

{

  "errors" : [ {

    "code" : "Neo.ClientError.Security.Unauthorized",

    "message" : "No authentication header supplied."

  } ]

}

You can remove data/dbms/auth and try neo4j-admin again 

And then provide -u neo4j:password to curl for auth

But I still get "Invalid username or password."" on

curl -H "Accept: application/json; charset=UTF-8" -H "Content-Type: application/json" -X POST -u neo4j:newpass1 http://localhost:7474/db/data/cypher -d '{

>   "query" : "CREATE (n:Person { name : {name} }) RETURN n",

>   "params" : {

>     "name" : "Foo"

>   }

> }'

{

  "errors" : [ {

    "code" : "Neo.ClientError.Security.Unauthorized",

    "message" : "Invalid username or password."

  } ]

}

Steps performed:

1. sudo rm /var/lib/neo4j/data/dbms/auth

2. sudo neo4j-admin set-initial-password newpass1

3. curl for auth 

curl -H "Accept: application/json; charset=UTF-8" -H "Content-Type: application/json" -X GET -u neo4j:newpass1 http://localhost:7474/

{

  "management" : "http://localhost:7474/db/manage/",

  "data" : "http://localhost:7474/db/data/",

  "bolt" : "bolt://localhost:7687"

}

4. Create a new node 

curl -H "Accept: application/json; charset=UTF-8" -H "Content-Type: application/json" -X POST -u neo4j:newpass1 http://localhost:7474/db/data/cypher -d '{

>   "query" : "CREATE (n:Person { name : {name} }) RETURN n",

>   "params" : {

>     "name" : "Foo"

>   }

> }'

{

  "errors" : [ {

    "code" : "Neo.ClientError.Security.Unauthorized",

    "message" : "Invalid username or password."

  } ]

}

Did i miss something?

http://localhost:7474/

this endpoint is unauthenticated: http://localhost:7474/

use to test: http://localhost:7474/db/data/

use /db/data/transaction

not sure how the old endpoint works with regard to auth

From our team:

Not Nginx specifically. Internally we use a Haproxy reverse proxy. I think the only things we've had to do are set an explicit timeout for the tunnelled connections (2 min) and configure it to log at the start of a connection (because connection pooling makes disconnection rare).

I think nginx is causing connection refused on localhost:7474

Do you have the settings for nginx?
