In the corporate world Windows still rules supreme. One reason for that is most enterprises rely on Microsoft Active Directory (AD) to manage users and connect them with network resources. With the just-released Ubuntu 21.04, aka Hirsute Hippo, that could change.
There are ways to do this in Linux -- Native LDAP and Kerberos PAM and NSS modules; Samba Winbind; and System Security Services Daemon (SSSD) -- but they're not easy. There are also third-party programs such as Centrify Authentication Service that get Linux and AD on the same page. But Ubuntu 21.04 is the first major desktop Linux to come with AD support baked in.
Ubuntu 21.04 desktops can now join an AD domain at installation for central configuration. In turn, AD administrators can now manage Ubuntu workstations, which simplifies compliance with company policies.

For years, Ubuntu has been enormously popular with Linux fans and developers. The corporate desktop? Not so much. Now, with Microsoft Active Directory integration, Ubuntu wants to be an enterprise business desktop as well.
