# Neo4j 4.4 impersonation demo

This is a simple application that demonstrates how to configure impersonation.

## Database setup

Start a [Neo4j](https://neo4j.com) server.

On the system DB, run:

```cypher

-- create home DBs & users & roles

CREATE DATABASE joesDb

CREATE DATABASE janesDb

CREATE USER joe SET PASSWORD 'joespass' SET HOME DATABASE joesDb

CREATE USER jane SET PASSWORD 'janespass' SET HOME DATABASE janesDb

CREATE ROLE impersonated

GRANT ROLE impersonated TO joe,jane

GRANT ALL GRAPH PRIVILEGES ON HOME GRAPH TO impersonated

CREATE ROLE impersonator

GRANT IMPERSONATE (joe, jane) ON DBMS TO impersonator

GRANT ROLE impersonator TO neo4j

-- init data ("joesDb" DB)

```

On `joesDb` DB:

```cypher

CREATE (:FavouriteMovie {title: 'Alien vs. Predator vs. CVE-2021-44228'})

```

On `janesDb` DB:

```cypher

CREATE (:FavouriteMovie {title: 'Roundhay Garden Scene'})

```

On `neo4j` DB:

```cypher

CREATE (:FavouriteMovie {title: 'The Matrix'})

```

## Run

`neo4j` impersonating `joe` in autocommit transaction:

```shell

go run ./cmd/autocommit

```

`neo4j` impersonating `jane` in a transaction function:

```shell

go run ./cmd/tx_func

```
