Introduction
You can assign multiple custom RADIUS attributes to each service or each
Customer. When a user is successfuly authenticated by the RADIUS server and an
Access_Accept packet is about to be sent, server will check the Custom
Attributes of the related Service and Customer. If there is any Custom
Attributes assigned to the service or Customer, all those attributes along with
their pre-defined values will be added to the packet.
For example, you can define different Filter-ID, Framed-Compression or
bandwidth values for different services.
To use this feature, you must enable LoadCustomAttributes switch in
config file. For more information see Using Custom
Attributes.
Processing Order
If any attribute is specified more than once, the last occurance of that
attribute will be used. You can specify which Attribute Value should be added
first using the "Order" parameter. "Order" is a numeric integer value which
specifies the order in which Custom attributes are processed. This order is
shared between those Custom Attributes assigned to a Service and those assigned
to a Customer. It means by using Order parameter, you can specify a certain
Custom attribute assigned to a customer is processed before a Custom attribute
assigned to a Service and therefore, the one from Service will override the one
from Customer (if same RADIUS attribute is used).
Conditional Custom Attributes
It's possible to add a Custom Attribute to a RADIUS response packet based on
value of another attribute. If an Attribute name is entered in the "Evaluate
Attribute" box, at the time of processing the Custom Attribute, it's value
will be checked against "Value" using the evaluation relationship specified
by "Is" dropdown. "Evaluate Attribute" name must be defined in Dictionary file.
A special value of "Client-IP-Address" can also be used for scenarios when
NAS-IP-Address does not match the IP address of the client (device communicating
with RADIUS server).
If no Attribute name is entered in the "Evaluate Attribute" box, Custom Attribute
will be added to all response packets.
