The supplier will automatically update the consumer when it contacts the 
consumer.  The supplier attempts to contact the consumer periodically.  
It uses a backoff strategy that has a maximum time of 5 minutes.  So at 
most, the consumer will be about 5 minutes behind the supplier.

It doesn't.  There is no way for the consumer to contact the supplier 
directly.  If 5 minutes is too long, there is a way for an operator to 
force sending updates.  You can do this using ldapmodify - modify the 
replication schedule in the replication agreement entry to "close the 
window" e.g. use something like 0000-0001 0 (i.e. replicate between 
midnight and 12:01 Sunday morning).  Then, immediately change the 
schedule back to what it was (usually 0000-2359 * or "* *").  This will 
have the effect of forcing the supplier to send all of its updates 
immediately.
