33.7. Module Access Control

As Chapter 52 explains, it is possible to restrict what a Webmin user can do with a module to which he has been granted access. For the Fetchmail module, you can limit the UNIX users for whom he can edit Fetchmail configurations. Once a user has been created, you can further restrict access by following these steps:

1.
In the Webmin Users module, click on Fetchmail Mail Retrieval next to the name of the user. This will bring up the module access control form.

2.
Change the Can edit module configuration field? to No to stop the Webmin user from switching the module to single-file mode or changing the path to the Fetchmail program.

3.
The Can edit fetchmail config for field determines for which UNIX users this Webmin user can edit Fetchmail servers. The available options and their meanings are:

All users The configuration of any user can be edited. This is the default.

Current Webmin user Only the UNIX user whose username is the same as the Webmin user can be edited. This option can be useful for allowing people to edit their own Fetchmail settings, although the Usermin program is a better alternative.

Only users Only the configurations of users entered into the text field next to this option can be edited.

All except users The Fetchmail settings for all users except those entered into the adjacent text field can be edited.

4.
Click the Save button to make the new module restrictions active.

This kind of access control is only useful if the module has been configured to allow the editing of individual .fetchmailrc files. In single configuration file mode, no restrictions apply.
