<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

is that not supported ? or something I configured wrong?<o:p></o:p></p>

<p class="MsoNormal">I setup Windows authentication by referring this link:<o:p></o:p></p>
