smbj - STATUS_ACCESS_DENIED for DFS

Hi here is my code that I am trying to test a DFS configuration

     SmbConfig config = SmbConfig.builder()
            .withMultiProtocolNegotiate(true)
            .withSigningRequired(true)
            .withDfsEnabled(true)
            .build();

    this.client = new SMBClient(config);
    this.connection = client.connect(serverName);
    this.ac = new AuthenticationContext(username, password.toCharArray(), domain);
    this.session = connection.authenticate(ac);
    this.share = (DiskShare) session.connectShare(sharename);

    for( FileIdBothDirectoryInformation item : this.share.list("myprojectname\\testfoldername") ){
        System.out.println(item.getFileName()+" ");
    }

   File f = this.share.openFile("myprojectname\\testfoldername\\try-a-new-file.txt",
            new HashSet<>(Arrays.asList(AccessMask.FILE_ADD_FILE)),
            new HashSet<>(Arrays.asList(FileAttributes.FILE_ATTRIBUTE_NORMAL)),
            SMB2ShareAccess.ALL,
            SMB2CreateDisposition.FILE_OPEN_IF,
            new HashSet<>(Arrays.asList(SMB2CreateOptions.FILE_DIRECTORY_FILE))
    );

I get the error at on the share.openFile line as

com.hierynomus.mssmb2.SMBApiException: STATUS_ACCESS_DENIED (0xc0000022): Create failed for .....

Why can this be happening, is it lock of permissions to create a file there? The interesting thing is I can connect to the same share via my Mac's Finder and can create files there, also tried with jcifs and it worked.
