Realms are a way of grouping users in RADIUS. Since RADIUSdesk is only a front-end for FreeRADIUS, realms are also supported by RADIUSdesk.
Realms and usernames
Normally, in RADIUS deployments, you can determine the realm a user belongs to based on the username.
Let us assume we have alice@my_realm.com. We can assume that Alice belongs to the my_realm.com realm.
RADIUSdesk allows you to follow this convention, but also gives you the flexibility to specify a user's email address as their username.
So you can register Alice with her gmail email address as her username.
We can now have the user alice.bodine@gmail.com which is part of the my_realm.com realm.
In RADIUSdesk ALL Vouchers and Permanent Users belongs to one realm.
BYOD devices automatically belong to the realm of the permanent user who owns the device.
Clouds and Realms
A cloud can contain zero or more realms.
The cloud thus becomes the owner of the realm.
So if you want an administrator to manage the users of a realm, make sure that they have administrator rights for the cloud under which the realm was created.
RADIUS Clients and Realms
If you add a RADIUS client, you have the option of only allowing network access to users from a specific realm (there can be several realms).
VLAN and PMK
You may have noticed these two buttons in the toolbar of the realm management applet
This is part of a new feature that is currently being developed and will be released soon.
