Implementing RADIUS Remote Authentication
Microsoft Active Directory can be used as source information for RADIUS authentication by installing the
Windows server component Internet Authentication Server.
If you choose RADIUS authentication protocol, complete the RADUIS fields as follows:
− Authentication Type: Click on the drop-down arrow to select either CHAP or PAP protocol.
− Server UDP Port / Custom UDP Port: Click on the drop-down arrow to select whether you
would prefer using standard RADIUS TCP port 1812, the legacy RADIUS TCP port 1645, or type
in your own user defined port in the Custom UDP Port field.
− Remote Accounting / Custom Accounting Port: Click on the check box to send authentication
events to a RADIUS accounting server; if so, type the TCP port should be used for transmitting
events in the Custom Accounting Port.
Returning User Group Information via RADIUS
When a RADIUS authentication attempt succeeds, Dominion KX 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.
