i saw the log files: Shutting down the service since there are data with invalid encryption. To continue, activate the 'EraseUndecryptableData' config flag by setting it to true in the config file to erase the invalid data.
but i wonder if i add that flag will i eraseanydata? the old one or new one? or should i take an backup?
(actually in qmc i couldn't configure the ldap but i dont know it is a cause or an effect )
