This may be a dumb question. I am a IT student and new to Linux. Is there anything similar to Active Directory for Linux? How do you join a domain on a Linux? Can Linux users be managed by a Microsoft Active Directory Domain Controller?
You can use AD authentification on Linux. Ubuntu for example has it already out of the box and you can choose it while installing. See: https://ubuntu.com/blog/new-active-directory-integration-features-in-ubuntu-22-04-part-1 You can even provide a AD Server with linux with Samba as a Active Directory Domain Contoller. More info here: https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller
Please don't post a question that has nothing to do with the topic of this thread in here. If you need help search the forums and create your own thread. Here is a guide about deleting files/folders: https://www.freecodecamp.org/news/how-to-remove-a-directory-in-linux/
