Hi,
the simple wy to do it is to use teh LDAP API instead of JNDI. JNDI is
by all mean atrocious anyway...
Otherwise, we have a class named NamingEnumerationAdapter which wraps a
EntryFilteringCursor, and this is what you want, I guess :
public NamingEnumerationAdapter( EntryFilteringCursor cursor )
throws NamingException
