I can't find anything in the global configuration that would make this work - the closest thing to it is the ability to designate which attributes can be set by a domain admin (by setting it as a zimbraDomainAdminModifiableAttr).
However, nothing seems to exist to limit the number of accounts per domain. Ideally there would be a setting in the domain attributes where you could specify maximum accounts, aliases, resources, and distribution lists which would not be modifiable by domain admins. The reason I think this is such an important idea is that Zimbra licensing is based on the number of user accounts, and it would be great to be able to set up various domains with a cap on the number of these available. |
