</div></div><p class="MsoNormal"> </p><p class="MsoNormal">Hi,<br><br>this may be related to same issue reported at:<br><a href="http://sip-router.org/tracker/index.php?do=details&task_id=114">http://sip-router.org/tracker/index.php?do=details&task_id=114</a><br>
<br>Therefore it can be just some log message printed erroneously. Can you dump the htable content (or print it with xlog) to see if the assignment is actually done or not?<br><br>Dumping the htable content:<br><br>kamctl fifo sht_dump a<br>
<br>Another possible issue I spot with your config is that you don't check for the existence of Authorization header. Since I am not using auth_radius, I am not sure radius_www_authorize() return -1 only when the password mismatches. Might be also when there is no header carrying the credentials. If no Authorization header is present, the $au is null -- in this case you just have to do www_challenge() and exit, since counting failed authentications for "<null>" user might bring you unexpected behaviour.<br>
