Hi , I would like to implement SSO for my Linux+Windows2012 machines with MFA.
I have installed FreeIPA, it works well for my Linux client authentication
with OTP enabled. However, for Windows client, I can only make it works with
FreeIPA without OTP.
The Windows machines are 2012 R2 without AD(workgroup only). When I login
Windows using FreeIPA user accounts enabled with OTP, it shows "An unsupported
preauthentication mechanism was presented to the Kerberos package", is that not
supported ? or something I configured wrong?
I setup Windows authentication by referring this link:
