That property has been moved to connection config in the latest snapshot of
ldaptive.

You can configure the round robin strategy to use it's invocation count,
rather than the connection count.
This behavior will be closer to what you expect for a connection pool.
<bean id="connStrategy"
class="org.ldaptive.provider.ConnectionStrategies$RoundRobinConnectionStrategy">
  <constructor-arg value="false" />
</bean
<bean id="jndiConfig" class="org.ldaptive.provider.jndi.JndiProviderConfig"
p:connectionStrategy-ref="connStrategy" />

Since connections will attempt to reopen themselves under certain failure
conditions, this doesn't guarantee that each new connection in the pool
will use the next URL.
But under nominal circumstances that's the behavior you will see.
I always like to point out that none of these software solutions are a good
substitute for a network load balancer.
