Chapter 12

Authentication Servers

The ArubaOS software allows you to use an external authentication server or the controller internal user database to authenticate clients who need to access the wireless network.

This chapter describes the following topics:

•"Understanding Authentication Server Best Practices and Exceptions" on page 168

•"Understanding Servers and Server Groups" on page 168

•"Configuring Servers" on page 169

•"Managing the Internal Database" on page 175

•"Configuring Server Groups" on page 177

•"Assigning Server Groups" on page 184

•"Configuring Authentication Timers" on page 187

Understanding Authentication Server Best Practices and Exceptions

•In order for an external authentication server to process requests from the Dell controller, you must configure the server to recognize the controller. Refer to the vendor documentation for information on configuring the authentication server.

Active Directory http://www.microsoft.com/en-us/server-cloud/windows-server/active-directory.aspx

Understanding Servers and Server Groups

ArubaOS supports the following external authentication servers:

•RADIUS (Remote Authentication Dial-In User Service)

•(Lightweight Directory Access Protocol)

•TACACS+ (Terminal Access controller Access Control System)

•Windows (For stateful NTLM authentication)

Additionally, you can use the controller’s internal database to authenticate users. You create entries in the database for users and their passwords and default role.

You can create groups of servers for specific types of authentication. For example, you can specify one or more RADIUS servers to be used for 802.1x authentication. The list of servers in a server group is an ordered list. This means that the first server in the list is always used unless it is unavailable, in which case the next server in the list is used. You can configure servers of different types in one group — for example, you can include the internal database as a backup to a RADIUS server.
