I guess this should be on top of the ldb/tdb patches?
Is a server with these and the ldb/tdb patches able to handle
a zarafa server which serves about 500-1000 users which make use of
the webmail interface? We have a customer were we used a OpenLDAP
proxy in front of the samba servers to handle the load.
The proxy was able to deliver responses under 10 msecs,
while samba needed about 350 msecs. The problem is that the proxy
db gets corrupted every few days.
