I have a network of Windows 7 PCs. And I am looking for a way to authenticate these computers through a centralized credential server. AD was one of the options but I don't have license for Windows server so I was trying to use Radius.

I installed freeradius on Ubuntu 22.04 and created users in the file /etc/freeradius/users.

But when it came to authenticating the Windows PCs against the Radius server, I couldn't find anything concrete. I know pGina can be configured to be used with radius but can we do it without downloading any external software?

Could anyone please advise?

  • Not sure if freeradius is possible but using Samba this should be possible: https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller – Robert Jul 13 '23 at 14:17
  • Can it authenticate a user who is trying to login into the PC through windows login screen? – Canonical Jul 13 '23 at 14:22

  • As far as I know Samba can host a domain with authentication support for the Windows computers and users. – Robert Jul 13 '23 at 15:42
  • @Robert So, Samba can act as AD DC. But if I need to authenticate switches, routers which natively supports radius authentication, can I use freeradius for those cases to authenticate against samba DC? – Canonical Jul 13 '23 at 17:20
