You must add users and a firewall protection profile to a user group before you can 
select Authentication. For information about adding and configuring user groups, see 

.

Select Authentication and select one or more user groups to require users to enter a 
user name and password before the firewall accepts the connection.

You can select Authentication for any service. Users can authenticate with the firewall 
using HTTP, Telnet, or FTP. For users to be able to authenticate you must add an 
HTTP, Telnet, or FTP policy that is configured for authentication. When users attempt 
to connect through the firewall using this policy they are prompted to enter a firewall 
username and password.

If you want users to authenticate to use other services (for example POP3 or IMAP) 
you can create a service group that includes the services for which you want to 
require authentication, as well as HTTP, Telnet, and FTP. Then users could 
authenticate with the policy using HTTP, Telnet, or FTP before using the other 
service.
