Mock returns data that it should not when searching by dn

[SirLefti]

I start the mock with the command line:

npx ldap-server-mock --conf=ldap-server-config.json --database=ldap-server-data.json

ldap-server-config.json:

{
    "port": 389,
    "searchBase": "dc=test"
}

ldap-server-data.json (just added another user):

[
    {
        "dn": "cn=user,dc=test",
        "attributes": {
            "objectClass": "person",
            "cn": "user-login",
            "attribute1": "value1",
            "attribute2": "value2"
        }
    },
    {
        "dn": "cn=user2,dc=test",
        "attributes": {
            "objectClass": "person",
            "cn": "user2-login",
            "attribute1": "value1",
            "attribute2": "value2"
        }
    }
]

When requesting the first user by its dn, I am getting both users instead:

ldapsearch -x -H ldap://127.0.0.1:389 -b "cn=user,dc=test"

# user, test
dn: cn=user,dc=test
objectClass: person
cn: user-login
attribute1: value1
attribute2: value2

# user2, test
dn: cn=user2,dc=test
objectClass: person
cn: user2-login
attribute1: value1
attribute2: value2

I can get the entry I want by using a filter instead, however the mock should not return entries that are not in the scope.
Am I missing something?
