TACACS Servers
You can now configure a TACACSserver as the authentication server to authenticate and authorize all types of
management users, and account user sessions. When configured, the TACACS server allows a remote access
server to communicate with an authentication server to determine if the user has access to the network. The
W-IAP users can create several TACACS server profiles and associate these profiles to the user accounts to
enable authentication of the management users.
TACACS supports the following types of authentication:
l ASCII
l PAP
l CHAP
l ARAP
l MS-CHAP
The TACACS server cannot be attributed to any SSID or wired profile in general as the authentication server
and is configured only for the W-IAP management users.
Dynamic Load Balancing between Two Authentication Servers
You can configure two authentication servers to serve as a primary and backup RADIUS server and enable load
balancing between these servers. Load balancing of authentication servers ensures that the authentication
load is split across multiple authentication servers and enables the W-IAPs to perform load balancing of
authentication requests destined to authentication servers such as RADIUS or LDAP.
The load balancing in W-IAP is performed based on outstanding authentication sessions. If there are no
outstanding sessions and if the rate of authentication is low, only primary server will be used. The secondary is
used only if there are outstanding authentication sessions on the primary server. With this, the load balance
can be performed across RADIUS servers of asymmetric capacity without the need to obtain inputs about the
server capabilities from the administrators.
Configuring an External Server for Authentication
You can configure RADIUS, TACACS, LDAP, and ClearPass Policy Manager servers through the Instant UI or the
CLI.
