Returning User Group Information via RADIUS

When a RADIUS authentication attempt succeeds, IP-Reach determines the permissions for a given user
based on the permissions of the user’s group.

Your remote RADIUS server can provide these user group names by returning an attribute, implemented as
a RADIUS FILTER-ID. The FILTER-ID should be formatted as follows:

Raritan:G{GROUP_NAME}

where

GROUP_NAME

is a string, denoting the name of the group to which the user belongs.
