ProSafe 20-AP Wireless Controller WC7520 Manage Authentication Servers and Authentication Server Groups You can specify three types of authentication servers: internal, external RADIUS, and external LDAP: • Internal authentication server. The wireless controller handles authentication. If you use this setting, set up Wi-Fi clients on the User Management screen (see Manage Users, Accounts, and Passwords on page 128.) • External RADIUS server. You can define a basic external RADIUS server that you would typically use in the profiles of a basic profile group of a small-scale network. You need to specify its configuration on the basic Authentication Server screen (see the next section) so that you can select this authentication option during the configuration of a profile. As part of the advanced authentication server settings, you can define multiple external RADIUS servers that you would typically use in a more complex network with many profiles. You can then assign different RADIUS servers to different profiles. By default, the external RADIUS server for the basic authentication group is called basic-Auth. You cannot change this name. By default, the external RADIUS authentication servers for the advanced authentication groups are called Auth1 through Auth8, and you can change these names. You can assign the basic-Auth server to an advanced profile group, and you can assign a RADIUS server of an advanced authentication group to the basic profile group. See the following configuration guidelines for external RADIUS servers: - For configuration guidelines for external MAC authentication, see Guidelines for External MAC Authentication on page 118. - For configuration guidelines for external authentication of captive portal users, see Configure Captive Portal Settings on page 126. • External LDAP server. You can define one external LDAP server (commonly referred to as an Active Directory [AD] server). You need to specify its configuration on the basic Authentication Server screen (see the next section) so that you can select this authentication option during the configuration of a profile. By default, the external LDAP server for the basic authentication group is called basic-LDAP. You cannot change this name, and you cannot configure any LDAP servers for the advanced authentication groups. You can assign the basic-LDAP server to both the basic profile group and to advanced profile groups. All three servers can be active so that the profiles that you set up can be configured to work with different authentication servers. For example, you could set up a guest profile with no authentication, an engineering profile that uses external RADIUS authentication, and a marketing profile that uses external LDAP authentication. The settings that you specify on the Authentication Server screen affect the selections available in the Network Authentication drop-down list and the corresponding Authentication Server field on the Edit Profile screens (see Figure 36 on page 77 and Figure 39 on page 86.)
