LDAP - Spring Boot |Getting javax.naming.CommunicationException | Connection Refused

I am using unboundid-ldapsdk As a LDAP Server. Getting Connection Refused When I try to Access My Rest End Point. I have Set up Port in My application.properties file. I've tried to run ldap sever on different Ports but Still getting the Same Error. My Properties file Look Like this.

spring.ldap.embedded.port=3268
spring.ldap.embedded.ldif=classpath:ldap-data.ldif
spring.ldap.embedded.base-din=dc=springframework,dc=org

And My LDIF File Looks Like this that is copied from https://spring.io/guides/gs/authenticating-ldap/

Class that Extends WebSecurityConfigurerAdapter 

@EnableWebSecurity
public class SpringSecurity extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.ldapAuthentication().userDnPatterns("uid={0},ou=people").groupSearchBase("ou=groups").contextSource()
                .url("ldap://localhost:3268/dc=springframework,dc=org").and().passwordCompare().passwordEncoder(new BCryptPasswordEncoder())
                .passwordAttribute("userPassword");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin();
    }
}

And a simple Rest EndPoint.

@RestController
public class HomeResource {

    @GetMapping("/")
    public String sayhello() {
        return "hello";
    }
}

I've looked everywhere but still not able to resolve this.

I had 2 entries in pom.xml for unboundid-ldapsdk due to which i was getting the same javax.naming.CommunicationException | Connection Refused. Solution is to keep only the one dependency without scope=test.

Problem:

<dependency>
    <groupId>com.unboundid</groupId>
    <artifactId>unboundid-ldapsdk</artifactId>
</dependency>
<dependency>
    <groupId>com.unboundid</groupId>
    <artifactId>unboundid-ldapsdk</artifactId>
    <scope>test</scope>
</dependency>

Solution:

<dependency>
    <groupId>com.unboundid</groupId>
    <artifactId>unboundid-ldapsdk</artifactId>
</dependency>

There was a typo in application.properties. Changed this

spring.ldap.embedded.base-din=dc=springframework,dc=org

to

spring.ldap.embedded.base-dn=dc=springframework,dc=org
