TL;DR The UnboundID LDAP SDK for Java has much friendly API and zero dependencies.

Apache Directory Service vs UnboundID LDAP SDK
1. Apache Directory Service is quite heavy stuff compare to our requirement, we just need a embedded LDAP server for UT.
2. The API of Apache Directory Service and Java Naming are not straightforward, because it's not specifically designed for LDAP.
3. Apache Directory Service provided a single fat-jar contains dependencies which aren't relocated.
