In my webpage I wanted to change the password of some accounts. So I got a script powershell. In this one I need to import the module Active-Directory to change the password of accounts. My server is on CentOS, so I install powershell on it. But when I do : Import-Module ActiveDirectory, the console return 'Import-Module: The specified module 'ActiveDirectory' was not loaded because no valid module file was found in any module directory.' Thanks
