Thank you for your response.
We already execute the command: /opt/opendj/bin/import-ldif -n userRoot --offline -l backup.ldif with opendj offile and the same issue with the LDAP happens. The o=gluu dn is being removed. The cmd show us the following error message:
category=TOOLS severity=ERROR msgID=96 msg=An error occurred while attempting to process the LDIF import: The database environment could not be opened: org.forgerock.opendj.config.server.ConfigException: An error occurred while trying to decode the managed object configuration entry ds-cfg-attribute=sid,cn=Index,ds-cfg-backend-id=userRoot,cn=Backends,cn=config: The Backend Index could not be decoded due to the following reason: The value "sid" is not a valid value for the "attribute" property, which must have the following syntax: OID.
We don't understand what does this mean. I hope you can help us!
Thank you again.
