        Cyclades ACS 5000 Advanced Console Server Command Reference Guide

To configure a authentication server:

1.

On the server, add raccess service to the user configuration.

2.

Define to which group or groups the user belongs.

user = <username>{

global = cleartext “<password>”

service = raccess{

group_name = <Group1>[,<Group2,...,GroupN>];

}

}

To configure user permission on the  server:

1.

On the  server, open the file /etc/tacacs/tac_plus.cfg. 

NOTE: 

The location of this configuration file may be different on your Linux distribution.

2.

Edit the parameters as per the following example. Refer to Table 3.7 for descriptions.

user = tomj{

    name = "Tom Jones"

    service = raccess {

       port1 = LAB2/ttyS2

       port2 = 192.168.0.1/ttyS1

       port3 = CAS/ttyS1

       port4 = 172.32.20.10/ttyS6

       port5 = LAB1/ttyS7

       port6 = Knuth/ttyS16

    }

}

Table 3.7: Parameters for Specifying User Authorization on a Server 

Parameter

Description

user = 

<username>

Defines the username as specified on the console server.

name = 

<"optional 

description">

To specify additional information about the user (optional).
This parameter must include quotes. The maximum number of characters 
allowed is 256. Adding more than 256 characters stops the server from 
restarting and produces a FAILED message at the time of authorization.
