Hi, >> yes, but in theses videos he use ldap from gluu Sorry but not sure what you wanted to mean?

I wanted to create LDAP users from a Java program, but I can´t connect to the gluu ldap server `Root exception is java.net.ConnectException: Connection refused: connect`, so I want to copy data from another ldap "server:389" to the gluu ldap, because I can create users from Java in ldap "server:389".

Please search knowledge base, someone asked same question before.

https://support.gluu.org/identity-management/4253/cant-connect-to-openldap-externally/ "Yes, by default it's not allowed to read Gluu ldap data from outside. You can create a reverse tunnel to your Gluu Server's ldapS address and then use this tunneling to access ldap data with your ldap browser." What is reverse tunnel? Is there any way to create ldap users from java? Thanks.

>> What is reverse tunnel? That is a system administration term. >> Is there any way to create ldap users from java? It depends what type of 'creation' you are trying to achieve and why. User creation can be done: - With Gluu Server oxTrust admin panel. - With SCIM - Can be pulled from backend AD through Cache Refresh. - Or directly with your ldap browser.

Flavio did you get your issue resolved?
