A reseller with Disk and/or Bandwidth limits are able to create an account with these settings set to unlimited. The account will be assigned to the default package and ignore the actual package settings.
If a reseller is granted the Account Modification
edit-account privilege, this allows them to create accounts without specifying a package. This causes the newly created account to be set to the default package but with unlimited values for disk/bandwidth, regardless of the package settings.
The Account Modification
edit-account privilege is listed under the Superuser category. If a reseller should be restricted to resource limits we advise against providing them Superuser level privileges. Instead, if you wish for your resellers to be able to modify their account settings you should grant them the ability to edit packages or upgrade an account to a new package. These privileges are controlled by the ACL options "Upgrade/Downgrade Accounts upgrade-account", "Add/Remove Packages add-pkg", and "Edit Packages edit-pkg"
