<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;">Dear all,<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;">This week I&#8217;ve implemented TACACS in our Radiator setup and it is working correctly. I&#8217;ve got one issue at the moment though.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;"><o:p>&nbsp;</o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:&quot;Calibri&quot;,&quot;sans-serif&quot;">The thing I&#8217;d like to change is the &#8216;authorization expired&#8217; messages. Authorization works correctly until a logged in user has been idle for some time. Radiator logs shows
 a &#8216;no context found&#8217; message in this case, so it seems that Radiator already flushed the authentication cache. I&#8217;ve tried to set the &#8216;idle-time&#8217; and &#8216;timeout&#8217; values, but this doesn&#8217;t seem to change a thing. Please note that when this message appears Radiator
 hasn&#8217;t been restarted.<o:p></o:p></span></p>
