How to make LdapContextSource pointing to UnboundID InMemoryDirectoryServer?

I have a set of old automated test cases which are based on Spring LDAP framework. They connect to an external LDAP server. I am thinking about replacing the external server with an embedded one. The UnboundID InMemoryDirectoryServer appears attractive, especially if there is a way allowing Spring LDAP based clients to connect UnboundID-based embedded server. The question is: How to do it? I am new to LDAP, please help.

Solution

There is really not much difference between the case of an external and an embedded LDAP server. When configuring the LdapContextSource, you will have to set the url of the server to something like ldap://localhost:33389/ (assuming your embedded server listens at port 33389).

Be aware that by default the UnboundID InMemoryDirectoryServer will pick a free port randomly at runtime unless you configure it to listen to a fix port. This might help you getting started:

InMemoryDirectoryServerConfig config = 
        new InMemoryDirectoryServerConfig("dc=example, dc=com");

// make sure that the server listens on port 33389
config.setListenerConfigs(
        new InMemoryListenerConfig("myListener", null, 33389, null, null, null));

InMemoryDirectoryServer ds = new InMemoryDirectoryServer(config);

ds.startListening();

// import some test data from an ldif file
ds.importFromLDIF(true,"content.ldif");
