As Chapter 52 explains, the Webmin Users module can be used to limit what a user or group can do with a particular module. For this module, you can control exactly which hosts, groups, subnets, and shared networks a user can edit. This can be useful for granting a subadministrator the right to set options for only a few hosts within your server configuration, while preventing him from changing subnets and other hosts.
Once a user has been given access to the module, limit him to editing only certain hosts by following these steps:
Another common use of the DHCP Server module's access control page is limiting a user to the viewing and cancelling of leases only. This can be done by setting the Can view leases? and Can remove leases? fields to Yes and everything else to No. The user should also be denied access to all hosts, subnets, and so on, or possibly given read-only permissions.
