Checklist: Configuring the IAS server for authenticated switch access
| Step | Reference |
|---|---|
Review RADIUS and IAS concepts. |
|
Review IAS implementation best practices. |
|
Review IAS security issues. |
|
If you are using certificates for authentication, install a computer certificate on IAS server computers. |
|
Install IAS on the servers to be used as primary and backup IAS servers. |
|
Configure the properties of the primary IAS server, including the ports used and event log settings. |
|
Configure logging methods for user authentication and accounting requests. |
|
Add the Ethernet switches as RADIUS clients on the primary IAS server. |
|
Use the New Remote Access Policy Wizard to create a common policy for Ethernet access. |
|
If you are using certificate authentication and initially installing computer certificates on your Ethernet clients over an authenticated Ethernet connection, enable guest authentication. |
|
If you are using certificate authentication and initially installing a computer certificate on your Ethernet clients over an authenticated Ethernet connection, create a group named Guests and add the Guest account as a member. |
|
If you are using certificate authentication and initially installing computer certificates on your Ethernet clients over an authenticated Ethernet connection, use the New Remote Access Policy Wizard to create a custom policy for new Ethernet switch clients (clients that do not have computer certificates that are used in the authentication process). Set the NAS-Port-Type condition to Ethernet and the Windows-Groups condition to Guests. On the Dial-in Constraints tab of the profile, restrict the maximum session time to 10 minutes. On the Advanced tab of the profile, add the Tunnel-Type attribute with the value of Virtual LANs (VLAN), and then add the Tunnel-Pvt-Group-ID attribute with the VLAN ID value that corresponds to guest Ethernet clients. |
|
Copy the IAS configuration from the primary IAS server to the backup IAS server. |
|
Register the primary and backup IAS servers in the appropriate Active Directory domains. |
Enable the IAS server to read user accounts in Active Directory |
Verify the configuration of the Ethernet switches. Ensure that the RADIUS servers used for the Ethernet switch authentication and accounting are the IAS server computers. |

Note
- You can configure IAS in Windows Server 2003, Standard Edition, with a maximum of 50 RADIUS clients and a maximum of 2 remote RADIUS server groups. You can define a RADIUS client using a fully qualified domain name or an IP address, but you cannot define groups of RADIUS clients by specifying an IP address range. If the fully qualified domain name of a RADIUS client resolves to multiple IP addresses, the IAS server uses the first IP address returned in the DNS query. With IAS in Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition, you can configure an unlimited number of RADIUS clients and remote RADIUS server groups. In addition, you can configure RADIUS clients by specifying an IP address range.
