title: Flapdoodle fails with "authorization failed" error with Spring Boot v2.3.3
body: <p>We are upgrading our Spring Boot applications from from 2.2.5/7 to 2.3.3 and seeing unit test failure with Flapdoodle embedded MongoDb with error message <code>request fails with authentication failure message</code></p>
  <p>Can some please suggest any solution/workaround to the problems</p>
  <p>The Spring Boot application has the following:</p>
  <pre><code>spring boot : 2.3.3
  spring-boot-starter-data-mongodb : 2.3.3
  mongodb-driver-core : 4.0.5
  mongodb-driver-sync : 4.0.5
  de.flapdoodle.embed.mongo - 2.2.0
  de.flapdoodle.embed.process - 2.1.2
  </code></pre>
  <p>We have application repositories which are doing simple CRUD operations.</p>
  <p>Test Class definition.</p>
  <pre><code>_@RunWith(SpringRunner.class)
  @DataMongoTest
  @activeprofiles({ &quot;unit-test&quot;, &quot;integration-test&quot;})
  public class ScopeRepositoryTest {
  
  @Autowired
  private ScopeRepository scopeRepository;
  private Scope scope1;
  
  @Before
  public void setup() {
      scopeRepository.deleteAll();
  }
  }_
  </code></pre>
  <p>When we execute the test case test case fails on start up with below error:</p>
  <p><code>Thread-3] o.s.b.a.mongo.embedded.EmbeddedMongo : 2020-08-26T14:00:21.257+0530 I ACCESS [conn2] SCRAM-SHA-1 authentication failed for admin on admin from client 127.0.0.1:56763 ; UserNotFound: Could not find user admin@admin. admin/admin are username/password of local db name as admin</code></p>
  <p>With older version of spring boot 2.2.5/7 and related mongodb packages, it works fine.</p>
