Setup an embedded LDAP server with spring security using Java config - spring

Question

I get spring security to work with a LDAP server running on my local machine, then, I move on to finish this tutorial https://spring.io/guides/gs/authenticating-ldap/ (not step by step, since I am not using Spring boot)
The goal is to run spring security with an "embedded" LDAP server, but I am having trouble setting things up.
to summarize
locally running LDAP(get it to work) vs. embedded LDAP(having trouble)
To configure AuthenticationManagerBuilder, I did
auth.ldapAuthentication()
.contextSource()
.root("dc=oreilly,dc=com") // I didn't set url() here, so embedded server can be used
.ldif("classpath:spring-security.ldif")
.managerDn("uid=admin,ou=system")
.managerPassword("secret")
.and()
.userSearchFilter("uid={0}");
in my pom.xml, I included the following libraries
<dependency>
<groupId>com.unboundid</groupId>
<artifactId>unboundid-ldapsdk</artifactId>
</dependency> <!-- This is the ldap server-->
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-ldap</artifactId>
</dependency>
I won't include other code here, since I get them to work with a local LDAP.
When I run, I get the following error:
java.lang.NoClassDefFoundError:
org/apache/directory/server/core/partition/Partition
I think I may miss to include some libraries, but not sure which..

After trying different setting, this works for me:
<dependency>
<groupId>org.apache.directory.server</groupId>
<artifactId>apacheds-protocol-ldap</artifactId>
<version>1.5.5</version>
</dependency>
<dependency>
<groupId>org.apache.directory.shared</groupId>
<artifactId>shared-ldap</artifactId>
<version>0.9.15</version>
</dependency>
