Guys, I am not sure if this fits here, but did anybody of you have a look at privacyIDEA? They provide a oss solution of a feature-rich 2fa server, that among other things even provide a free oss credentialprovider that would enable windows login with 2fa. One just has to compile it onself with Visual Studio, and I believe that a full integration in nethserver could be a great improvement! I had a look at it and the server was easy to install in centos and configure it to query neth ad. After some tinkering I was able to compile their credentialprovider (but I unfortunatelly had no time to integrate it in our windows 10 clients). In the end the need for 2fa for the windows login was considered nonessential in our case, so I focused on other stuff, but from what I had discovered this could be a really good allinone solution for 2fa so I thought, I’d mention it here just in case someone would like to have a look at it.
