Spring Native image tests: InvalidEntryException: Can't get Id field when using @DataLdapTest

Hello,

i tried to create a @DataLdapTest, as seen here.

This test runs fine on the JVM, but when run with gradle nativeTest, this fails with:

  JUnit Jupiter:DataLdapTests:saveAndLoad()
    MethodSource [className = 'example.ldap.odm.DataLdapTests', methodName = 'saveAndLoad', methodParameterTypes = '']
    => org.springframework.ldap.odm.core.impl.InvalidEntryException: Can't get Id field from Entry Person{dn=cn=John Doe,ou=company1,c=Sweden,dc=spring,dc=io, fullName='John Doe', lastName='Doe', description='Test user', country='Sweden', company='company1', phone='+46 555-123123'}

I'm not sure if this is a bug in Boot or in SF.

After a first quick look, does not look like a Framework issue.

Since this use case seems similar to http client ones, could you try to add a @RegisterReflectionForBinding(Person.class) annotation to the sample ?

cc @jzheaux since that's related to https://github.com/spring-projects/spring-ldap/.

Oh sorry, i was under the impression that the LDAP code is in SF, sorry about that.

The strange thing is that this is running fine in native image when starting the application, but it fails in JUnit tests.

I'll close this issue and reopen it on the spring-ldap tracker.
