LDAP communication error

Question

I am using this below code to connect to the ldap and assigning roles to the users.

    IdentityStoreFactoryBuilder builder =
            new IdentityStoreFactoryBuilder();
        IdentityStoreFactory oidFactory = null;
        IdentityStore oidStore = null;
        Hashtable factEnv = new Hashtable();
        Hashtable storeEnv = new Hashtable();
        factEnv.put(OIDIdentityStoreFactory.ST_SECURITY_PRINCIPAL, "Obu");
        factEnv.put(OIDIdentityStoreFactory.ST_SECURITY_CREDENTIALS,
                    "password123");
        factEnv.put(OIDIdentityStoreFactory.ST_LDAP_URL,
                    "ldap://localhost:3060/");// here i'm getting exception
        oidFactory =
                builder.getIdentityStoreFactory("oracle.security.idm.providers.oid.OIDIdentityStoreFactory",
                                                factEnv);
        storeEnv.put(OIDIdentityStoreFactory.ADF_IM_SUBSCRIBER_NAME,
                     "dc=us,dc=oracle,dc=com");
        oidStore = oidFactory.getIdentityStoreInstance(storeEnv);

Exception stack trace is:

Answer 1

Nothing listening at the port. Where did you get port 3060 from? The usual LDAP port is 389, or 636 for LDAPS.

Answer 2

java.net.ConnectException: Connection refused means The port name you have specified for the LDAP server is incorrect. Also check for other parameters you are passing those are making it unreachable.

Answer 3

I got the same error. coz I did not give some below props in application.properties. please do not forget to give those props.

spring.ldap.embedded.ldif = classpath:test-server.ldif
spring.ldap.embedded.base-dn = dc=springframework,dc=org
spring.ldap.embedded.port = 8389
