<div><font color="#0000CC"> </font></div>
<div><font color="#0000CC">On Red Hat Enterprise Linux 5, I wish to create a login module that would require the “consent” of two users before either could login.</font></div>
<div><font color="#0000CC"> </font></div>
<div><font color="#0000CC">I have already modified the pam_radius module to perform a few of the things I need and I know where to “intercept” the authentication process to control whether it is successful or not. When authenticating for sudo, the modified
code seems to perform most of what I want. However, my problem is with initial system login.</font></div>
<div><font face="Calibri" size="2" color="#0000CC"><span style="font-size:11pt;"> </span></font></div>
<div><font color="#0000CC">What I cannot figure out is how to provide a prompt during the initial system login so that the two users can “interact”. I need to be able to do the following:</font></div>
<div><font color="#0000CC"> </font></div>
<ol style="margin:0;padding-left:36pt;">
<font color="#0000CC">
<li style="margin-bottom:6pt;">Provide a standard login prompt and accept the users PIN + Token</li><li style="margin-bottom:6pt;">Generate and display a random number</li><li style="margin-bottom:6pt;">Provide a prompt where that random number can be typed in</li></font>
</ol>
<div><font color="#0000CC">My experience with the pam_radius module gives me confidence that I can code the underlying “logic” of the process. What I can’t figure out is where do I code the prompts? There are suggestions that it is in one of the “getty” type
processes, but I cannot figure it.</font></div>
<div><font color="#0000CC"> </font></div>
<div><font color="#0000CC">Any help would be very much appreciated, including the suggestion that what I’m trying to do is either ill-advised (I’m not sure why that would be) or extremely difficult (i.e. requires modifying the core kernel).</font></div>
<div><font color="#0000CC"> </font></div>
<div><font color="#0000CC">Thank you.</font></div>
