Hi Tom,

I've managed to improve performance significantly by using the source id (as
it wasn't in OpenLDAP initially) and by setting the initial-cache-size for
both groups and subjects to what are suitably large values :-)
I've given Grouper a little bit more memory to play with too as it was having
issues with garbage collection.

OK that seems fairly sensible however as I'm using a "bushy" structure in
ldappc.xml I'm wondering if I can get away with setting the same root-dn? Or
is there a way of telling it not to create the ou=<stem-name> ou?

Kind regards,
