Linking Ressources From Client to Domain

[defcode]

Hello,

I've searched but didn't found the solution so here is my problem if anyone could help:

In Plesk 8.x when you set for example 500MB of space to a client, the domain in this client couldn't use more than 500MB as a limit but now in plesk 9 if i set a limit of 500MB to a client i can set 50000MB or even unlimited to the domain name. Anyway to block this in plesk 9 ? I've tryed the overuse setting but seems not to do the trick.

Sorry for my bad english.

Thanks
