Unsupported authentication token, scheme='none' only allowed when auth is disabled:

[fme_mrc]

Hi Im trying to access the neo4j Server from my JDBC application , However im getting unsupported authentication token error . I'm able to access the Neo4j browser with same credentials.

Below is my code :

public class neojdbc  {

	public static void main(String[] args) {
		
		
		Config noSSL = Config.build().withEncryptionLevel(Config.EncryptionLevel.NONE).toConfig();
        Driver driver = GraphDatabase.driver("bolt://XX.XX.XX.XX:7687",AuthTokens.basic("neo4j","test123"),noSSL); // <password>
        
        try (Session session = driver.session()) {

              List data = 
              asList(asList("Jim","Mike"),asList("Jim","Billy"),asList("Anna","Jim"),
              asList("Anna","Mike"),asList("Sally","Anna"),asList("Joe","Sally"),
              asList("Joe","Bob"),asList("Bob","Sally"));
    
              String insertQuery = "UNWIND {pairs} as pair " +
               "MERGE (p1:Person {name:pair[0]}) " +
               "MERGE (p2:Person {name:pair[1]}) " +
               "MERGE (p1)-[:KNOWS]-(p2);";
      
               session.run(insertQuery,singletonMap("pairs",data)).consume();
          
               StatementResult result;
            
               String foafQuery = 
               " MATCH (person:Person)-[:KNOWS]-(friend)-[:KNOWS]-(foaf) "+
               " WHERE person.name = {name} " +
               "   AND NOT (person)-[:KNOWS]-(foaf) " +
               " RETURN foaf.name AS name ";
               result = session.run(foafQuery, parameters("name","Joe"));
               while (result.hasNext()) System.out.println(result.next().get("name"));
      
               String commonFriendsQuery =
               "MATCH (user:Person)-[:KNOWS]-(friend)-[:KNOWS]-(foaf:Person) " +
               " WHERE user.name = {from} AND foaf.name = {to} " +
               " RETURN friend.name AS friend";
               result = session.run(commonFriendsQuery, parameters("from","Joe","to","Sally"));
               while (result.hasNext()) System.out.println(result.next().get("friend"));
      
               String connectingPathsQuery =
               "MATCH path = shortestPath((p1:Person)-[:KNOWS*..6]-(p2:Person)) " +
               " WHERE p1.name = {from} AND p2.name = {to} " +
               " RETURN [n IN nodes(path) | n.name] as names";
               result = session.run(connectingPathsQuery, parameters("from","Joe","to","Billy"));
               while (result.hasNext()) System.out.println(result.next().get("names"));

		

	    }
} }

Below is my error

Facing the same problem when I am trying to connect to the Neo4j DB from my spark program using intellij, and I dont see any solutions.
@neo4j engg team , pls provide a template how to connect to neo4j not on spark console but using an IDE like intellij , that way app developers like us are helped .
this is a recurring issue but with no direct holistic solution, have tried all the hacks posted in all the forums
kindly revert this is already making feel not so encouraged with NEO4J , NOT EVEN GOT TO SOLVING THE BUSINESS AND TECH PROBLEM AND I'M BESETTED WITH A P1 BLOCKER

for the doubting Thomas who like to see the log

I in fact set the dbms.security.auth_enabled=true in the neo4j.conf file restarted the server and still this error persists
error:
org.neo4j.driver.v1.exceptions.AuthenticationException: Unsupported authentication token, scheme 'none' is only allowed when auth is disabled.

I tried changinging the
val driver: Driver = GraphDatabase.driver("bolt://localhost:7687",
AuthTokens.basic("neo4j", "neo4j"))

AuthTokens.basic to AuthTokens.none; still no Cigar.
is there no solution for this is middle earth????????????????????

[RoshanBaghwar]

Set the dbms.security.auth_enabled=false in the neo4j.conf file and restart the server
