With the new configuration option MASTER_ACCOUNT_OVERRIDE in /opt/open-xchange/etc/AdminDaemon.properties it is possible to enable the oxadminmaster accounts or the subadmin accounts when using the reseller bundle to do operations inside context. In other words it allows to act on behalf of the context admin.

When using the reseller bundle, subadmins allowed to act on behalf of context admins, must own either the context directly or must be a superadmin of the subadmin owning a context.
