Realms can be found in many RADIUS setups. YFi Hotspot Manager also features realms. This page explains typical usage of realms.
RADIUS setups of ISP's can grow quite huge.
Creating a realm in RADIUS helps segmenting the users. A realm adds a suffix to the user's username. The suffix is separated from the username by a delimiter character.
The standard used is the '@' sign.
Ths makes it easy to read, since it reads <username><at><realm>
The realm does not need to be the end part of a domain name EG yfi.co.za, but it makes things easy since most ISP's also provide e-mail and thus the user can use the email address as a username and email address.
Realms in YFi Hotspot Manager are used like the standard realms in RADIUS. It gives the option for extra information though.
A realm now have a human readable name instead of an encrypted suffix.
We also have an icon for a realm, an address and contact detail.
The suffix that you specify when creating a realm does not need to be the end part of a domain name, but can be.
The suffix must be unique though since the suffix can be seen as a group tying users together.
Each Voucher or Permananet User created through YFi Hotspot Manager has to be part of a realm - it is compulsory.
Yfi's realms can have one or more of the following tied to it, so be very carefull when you delete a realm.
Be carefull when you delete a realm since the knock-on effect may not be what you expected.
Once a Voucher or Permanent User user is created as part of a realm it is stuck with it for life!
