想在sharepoint里面加一个新的账户，但是不能直接在sharepoint sevrer上面直接加，需要在Activate Directory Users and Computers里面加。
click Start
click Windows Administrative Tools
click Activate Directory Users and Computers,will pop up an window
Click Users on left panel
click Action ->New->User, will pop up a New Object - User window
enter information and password on window to create user
after all, then go to sharepoint site, we can grant permission to new created user
