Chapter 11 User Authentication Kerio Control allows administrators to monitor connections (packet, connection, web pages or FTP objects and command filtering) related to each user. The username in each filtering rule represents the IP address of the host(s) from which the user is connected (i.e. all hosts the user is currently connected from). This implies that a user group represents all IP addresses its members are currently connected from. Besides access restrictions, user authentication can be used also for monitoring of their activities in the Kerio StaR interface (see chapter 21), in logs (see chapter 22), in the list of opened connections (see chapter 19.2) and in the overview of hosts and users (see chapter 19.1). If there is no user connected from a certain host, only the IP address of the host will be displayed in the logs and statistics. In statistics, this host’s traffic will be included in the group of not logged in users. 11.1 Firewall User Authentication Any user with their own account in Kerio Control can authenticate at the firewall (regardless their access rights). Users can connect: • Manually — by opening the Kerio Control web interface in their browser https://server:4081/ or http://server:4080/ (the name of the server is only an example — see chapter 12). It is also possible to authenticate for viewing of the web statistics (see chapter 21) at https://server:4081/star or http://server:4080/star Note: Login to the Administration interface at https://server:4081/admin or http://server:4080/admin is not equal to user authentication at the firewall (i.e. the user does not get authenticated at the firewall by the login)! • Automatically — IP addresses of hosts from which they will be authenticated automatically can be associated with individual users. This actually means that whenever traffic coming from the particular host is detected, Kerio Control assumes that it is currently used by the particular user , and the user is considered being authenticated from the IP address. However, users may authenticate from other hosts (using the methods described above). IP addresses for automatic authentication can be set during definition of user account (see chapter 16.1). 160
11.1 Firewall User Authentication This authentication method is not recommended for cases where hosts are used by multiple users (user’s identity might be misused easily). • Redirection — when accessing any website (unless access to this page is explicitly allowed to unauthenticated users — see chapter 13.2). Login by re-direction is performed in the following way: user enters URL pages that he/she intends to open in the browser. Kerio Control detects whether the user has already authenticated. If not, Kerio Control will re-direct the user to the login page automatically. After a successful login, the user is automatically re-directed to the requested page or to the page including the information where the access was denied. • Using NTLM — if Internet Explorer or Firefox/SeaMonkey is used and the user is authenticated in a Windows NT domain or Active Directory, the user can be authenticated automatically (the login page will not be displayed). For details, see chapter 25.3. User authentication advanced options Login/logout parameters can be set on the Authentication Options tab under Users and Groups → Users.
