Managing Linux® Systems with Webmin™ System Administration and Module Development

4.14. Module Access Control

It is possible to grant a Webmin user or group access to only a subset of features in the Users and Groups module. This is most commonly used to allow a subadministrator the right to edit only selected users and groups on the system, and to change their attributes in only limited ways. In a virtual hosting environment, for example, you may want to give a Webmin user the ability to create and edit up to 10 users with UIDs in a limited range, and home directories under a fixed directory. These privileges give the user no way to gain root access and affect users that do not belong to him.
