I have implemented this exact solution with a Polish application (I'm based in Poland). And it worked. Although mine was using mysql for the user storage, but ldap was also an option.<br><br>Mine runs with a Java application on the mobile phone, which I've set to allow 60 second timings for the password validity.
<br><br>The application that is providing the one-time password functionality should integrate with the radius server without any major config changes.<br><br>You fail to mention the application your trying to use?<br><br>

Hi there,<br><br><br>i am trying to setup a time based one time password with the freeradius. (no<br>challange response !!)<br><br><br>i have a mobile phone that produces a token.<br>the token is a md5-hash of a shared-secret and the actual time in ms.
<br><br>now i want to configure the freeradius server the following way:<br><br>the user has to enter his uername and the produced token from the mobile<br>phone.<br>this information is sent to the freeradius-server.<br>the server is connected to a ldap-database and looks up if the user exists.
<br>if the user exists, he gets the shared-secret from the ldap.<br><br>now the freeradius has to calculate some tokens (cause time on server and<br>mobile are not the same). md5 of the shared secret from the user from ldap
<br>and actual time.<br><br>after that he has to compare the calculated tokens with the token that was<br>provided by the user.<br><br>on positiv matches the user is authenticated.<br><br>Can it be implemented? Is there literature that I need to have a look at?
<br>Is there already a plugin that supports time based one time passwords?<br><br>Can anyone help me with setting up this scenario???<br><br>best regards<br>peter urban<br><br>_________________________________________________________________
