Altaf, you have not provided even 10% of the information we need to help you. My guess is that you want to configure an LDAP client to use the Gluu OpenDJ server for authentication. Please provide the following information:
1. What client are you using?
2. What is the BindDN, BaseDN, host, port, and base DN that you are using for your client configuration?
3. LDAPS (tcp/1636) is not open by default on the Gluu Server. Can you even connect to it?
4. Have you imported the self-signed ldap cert into your client (or are you using trust-all)?
5. Have you checked the [OpenDJ 3.0 admin guide](https://backstage.forgerock.com/#!/docs/opendj/3)? We have almost no modifications to the base distribution.
6. Is there a reason you are not using 2.4.3?
BTW, if I am wrong, and you are trying to configure cache refresh as Alex thinks, please attach screenshots with all screens so we can see how you are configuring it. Also, we'd need to see the oxtrust cache refresh log.
