Assign Authentication for WebVPN
Assignment of an authentication server group to WebVPN is the final step to enable basic
WebVPN functionality. You must configure at least one authentication server group on the
ASA 55X0 Security Appliance before an authentication group to the WebVPN service can be
assigned. The authentication-server-group group tag command is used while in WebVPN
mode to assign one or more authentication server groups to the WebVPN service. This
command can also be used within the pop3s, imap4s, and smtps subcommand modes to
assign authentication for specific e-mail proxies.
