Hi, Alexandre.
It's a known issue. Here is hot-fix:
1. Log in to container
2. Retrieve the correct schema file: `# wget https://raw.githubusercontent.com/GluuFederation/community-edition-setup/version_4.1.0/static/opendj/101-ox.ldif`
3. Stop "opendj" service
4. Backup previous schema file (you'll need it to rever the change if something will go wrong): `# cp /opt/opendj/config/schema/101-ox.ldif ./101-ox.ldif.bak`
5. Deploy the new schema: `# cp 101-ox.ldif /opt/opendj/config/schema/101-ox.ldif`
6. Start the service; check `/opt/opendj/logs/server.out` for any schema-related errors; if something goes wrong, restore the schema from the backup and restart the service
Sorry for the inconvenience caused, this is fixed in 4.2 already.
