Restriction in RADIUS NT 2.0


Livingston RADIUS NT 2.0 requires a database engine called DAO
for caching purposes. DAO is included with RADIUS NT 2.0 and should
be installed prior to installing RADIUS. If your NT server or workstation
doesn't have DAO, refer to the DOWNLOADING RADIUS NT 2.0 section
to install DAO.


RADIUS NT 2.0 includes the following features:

1. Group is supported in RADIUS NT 2.0. Group is used only when
Auth-Type = System. When Group is specified as a check-item in the
user profile, only users within that group can be authenticated.
Group can be defined as a local group (available on Windows NT
workstation) or global group (available on Windows NT server).

The Group attribute must be a string with a length of up to 63
printable ASCII characters.

If multiple Groups are defined, in order for the user to
authenticate, that user must belong to all those Groups.
The check-item line in the RADIUS user profile can have up to 255

Example of user profile with one Group:

username Auth-Type = System, Group = "Engineering"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address =,
Framed-Routing = None,
Framed-Compression = Van-Jacobson-TCP-IP,
Framed-MTU = 1500

Example of user profile with two Groups defined:

username Auth-Type = System, Group = "Engineering", Group = "Guests"
Service-Type = Login-User,
Login-IP-Host =,
Login-Service = Telnet,
Login-TCP-Port = 23

2. When used in conjunction with ComOS 3.5 or later, the Password
in the RADIUS user profile can be up to 48 characters long.

3. The database mode of the RADIUS users file can be enabled as
a command in DOS to build the users database. To use this feature,
enter the following command at the DOS prompt:

c:\program files\livingston\RADIUS NT\radsvc.exe -builddbm

After the above utility is executed, the number of users in the
users file is logged into the Event Log. The Event Log is located
in Start | programs | Administrator Tools | Event Viewer.

In addition to the command line, the database mode can also be
enabled in the GUI by selecting the SetupOptions panel, under Users
Cache option, click on Enable Users Cache for Authentication.

4. Every time the Updated Users Cache option is selected to refresh
the users database, the number of users and DEFAULT entries in
the users file will be displayed on the popup window.

5. Support For Administrative Logins

When used in conjunction with ComOS 3.5 or later, RADIUS NT 2.0
provides the ability to authenticate administrative logins with
two classes of users:

* administrative users with full configuration ability
(everything that !root can do)

* read-only administrative users who cannot change the
configuration, but can reset ports, reboot, set debug flags,
and show status.

With this feature, rather than requiring everyone in a Network
Operations Center (NOC) to know the global administrative passwords
on all the PortMasters, an individual account to track
access and limit configuration changes to appropriate personnel
can be created.

In ComOS 3.5 and later, if a RADIUS Access-Accept returns a
Service-Type of Administrative-User (6), the PortMaster treats it
as a !root login. If a RADIUS Access-Accept returns a Service-Type of
NAS-Prompt-User, a restricted administrative login is granted that has
permission to use the following commands:

* ifconfig
* ping
* ptrace
* reboot
* reset
* set console
* set debug
* show
* traceroute
* Any other commands that do not affect the configuration

A NAS-Prompt-User does not have access to the following commands: add,
delete, erase, save, tftp, or any set commands other than "set debug"
and "set console".

Following are two examples of NAS-Prompt-User and Administrative-User
in the users file:

!pmmon Password = "dontuseth1s"
Service-Type = NAS-Prompt-User

!pmconfig Auth-Type = System, Prefix = "!"
Service-Type = Administrative-User

Caution - If you are using your RADIUS NT server with a combination of
Livingston products and other vendors' products, confirm the following:

* Make sure that these two Service-Types are not used or
* Other vendor implementation of these two Service-Types is
compatible with Livingston's implementation
