You just read the entry. LDAP does not have a read operation, so it 
must be simulated with a base object search. The search filter must be 
written to always match the entry - typically a filter of 
(objectclass=*) is used which will always work because every entry must 
have an objectclass attribute.

The reason that a filter of (dn=$dn) does not work is because entries 
do not typically have an attribute called 'dn'. Hence filtering on the 
attribute is usually meaningless.
