/**
* Wrapper class to handle the full identification of an LDAP entry. An LDAP entry is
* identified by its Distinguished Name, in Spring LDAP represented by the
* {@link DistinguishedName} class. A Distinguished Name can be absolute - i.e. complete
* including the very root (base) of the LDAP tree - or relative - i.e relative to the
* base LDAP path of the current LDAP connection (specified as base
to the
* {@link ContextSource}).
*
* The different representations are needed on different occasions, e.g. the relative DN
* is typically what is needed to perform lookups and searches in the LDAP tree, whereas
* the absolute DN is needed when authenticating and when an LDAP entry is referred to in
* e.g. a group. This wrapper class contains both of these representations.
