I think it will be easy to use the abstract syntax as defined by the
ojb.broker.query package for LDAP too.
You just need a translator that translates these expressions into LDAP
queries.
We have done exactly that in a project at my company.

I don't believe that there are a lot other things that might be reused for
an LDAP access in OJB. The PersistenceBrokerImpl is focussed on JDBC and
nothing else.

But: you might consider to let you tool implement the PersistenceBroker
interface!
This way OJB could be used to transparently serve relational databases AND
Ldap servers. 

HTH,

Thomas
