Someone could intercept the network packets and read the username and password being sent to the server. You can limit access to files and directories on your Compass Server by making them available only to people using specific computers. You specify hostnames or IP addresses for the computers that you want to allow or deny. You can use wildcard patterns to specify multiple computers or entire networks. If you want to use this feature, you must have DNS running in your network and your computer must be configured to use it.
Users can access the files and directories immediately without entering a username or password.
If the computer doesn't have access, the user will get a message denying access. It's possible for more than one person to have access to a particular computer. If both methods of authentication are used, the end user will have to enter a username and password before getting access. When you use access control on your server, the settings are stored in a file with the extension .acl . For example, the administration server uses the directory adminacl .
