The authentication model using RADIUS and LDAP

In the next example, on a Linux FreeRadius Server, the user has the “zoneAdmin” permissions, with

VFlist 2, 4, 5, 6, 7, 8, 10, 11, 12, 13, 15 17, 19, 22, 23, 24, 25, 29, 31 and HomeLF 1.

user300 Auth-Type := Local, User-Password == "password"

Brocade-Auth-Role = "zoneadmin",

Brocade-AVPairs1 = "HomeLF=1;LFRoleList=securityadmin:2,4-8,10”

Brocade-AVPairs2 = "LFRoleList=admin:11-13, 15, 17, 19;user:22-25,29,31"

The RADIUS server

NOTE

To set up the RADIUS server, you must know the switch IP address, in either IPv4 or IPv6 notation,

or the name to connect to switches. Use the ipAddrShow command to display a switch IP address.

For Brocade Backbones, the switch IP addresses are aliases of the physical Ethernet interfaces on

the CP blades. When specifying client IP addresses for the logical switches in these systems, make

sure the CP blade IP addresses are used. For accessing both the active and standby CP blade, and

for the purpose of HA failover, both of the CP blade IP addresses must be included in the RADIUS

server configuration.

User accounts should be set up by their true network-wide identity rather than by the account

names created on a Fabric OS switch. Along with each account name, the administrator must

assign appropriate switch access permissions. To manage a fabric, these permissions can be User,

Admin, and SecurityAdmin.

Configuring RADIUS server support with Linux

The following procedures work for FreeRADIUS on Solaris and Red Hat Linux. FreeRADIUS is a

freeware RADIUS server that you can find at the following website:

www.freeradius.org

Follow the installation instructions at the website. FreeRADIUS runs on Linux (all versions),

FreeBSD, NetBSD, and Solaris. If you make a change to any of the files used in this configuration,

you must stop the server and restart it for the changes to take effect.

FreeRADIUS installation places the configuration files in $PREFIX/etc/raddb. By default, the

PREFIX is /usr/local.

Configuring RADIUS service on Linux consists of the following tasks:

• Adding the Brocade attribute to the server

• Creating the user

• Enabling clients

Adding the Brocade attribute to the server

1. Create and save the file $PREFIX/etc/raddb/dictionary.brocade with the following information:

# dictionary.brocade
