memberOf overlay didn't put memberOf attributes on user records

[masch712]

050-openldap-populate appears to configure the memberOf overlay, then create the users and groups afterwards, but when I query my docker container for all users, I don't see a memberOf attribute on any of them.

Replication steps

1. Run the docker container:

docker run -d --rm -p 10389:10389 -p 10636:10636 rroemhild/test-openldap

2. Query for all users:

ldapsearch -H ldap://localhost:10389 -x -b "ou=people,dc=planetexpress,dc=com" -D "cn=admin,dc=planetexpress,dc=com" -w GoodNewsEveryone "(objectClass=inetOrgPerson)"

See that none of the users have a memberOf attribute.

Did I miss something? Sorry I'm a bit of a LDAP novice, I'm using this container to test LDAP integration from my application.

Ah, it appears that memberOf is an "Operational Attribute", so I need to append the "+" argument to my ldapsearch command.
This command returns the memberOf attribute:

ldapsearch -H ldap://localhost:10389 -x -b "ou=people,dc=planetexpress,dc=com" -D "cn=admin,dc=planetexpress,dc=com" -w GoodNewsEveryone "(objectClass=inetOrgPerson)" "+"
