Authentication It has been some time since Windows launched Integrated Network Authentication and a single logon system. Before Windows 2000, Windows NT domain controller (DC) used the nt lan Manager (NTLM) protocol to provide authentication services for Windows clients. Although NTLM is not as secure as originally imagined, it is still very useful. It perfectly

the functions of the proxy server as follows: 1. the disk space occupied by Squid can be automatically reclaimed under one condition; 2. Verify the user's identity using the user account information on the AD server to avoid repeated user information setting; 3. Three user permissions are provided: 1. Deny all permissions; 2. Internet access is allowed, but video, audio, and executable files cannot be downloaded; 3. unlimited access to any Internet resources; 4. IT administrators can vie

Starting from the current situation of the company, we can re-plan the functions of the proxy server as follows: 1. the disk space occupied by Squid can be automatically reclaimed under one condition; 2. verify the user's identity using the user account information on the AD server to avoid repeated user information setting; 3. three user permissions are provided: 1. deny all permissions; 2.

Login is going to do two things-first querying the user and then providing the user with the services they need, such as providing a shell program. Normally login requires the user to enter a name and password for authentication. When the user name is entered, the system will naturally be compared to whether the user is a legiti
