Hey all,<div><br></div><div> I thought I would never ask for help on here, it's more the other way around I'm the one helping out. Anyway here is what I have run into. I'm trying to get a simple VPN connection up and authenticate to a separate Radius server. Being that most of the clients are going to Winblows and to make it easy for the users to setup, my thought was to use PPTPD (poptop) with Radius. I spent a solid 8 hours trying to get PPTPD to authenticate to the Radius server but PPTPD isn't sending anything to the Radius server it works great with chap-secrets though. The Radius server is not the issue because it works great and is authenticating via LDAPS and I can authenticate on the same server I'm setting up the PPTPD server on via PAM. For example:</div>
<div><br></div><div>Adding the bellow line to /etc/pam.d/sshd</div><div>auth sufficient pam_radius_auth.so debug</div><div><br></div><div>I can ssh in and authenticate via Radius, my Radius logs show the connection and everything is happy. But on the same server PPTPD won't have anything to do with it. Now have also tried this on separate servers as well; with them running Ubuntu 9.4 to 10.4 with the same result, no packets are being sent to the Radius server. I have posted this to the POPTOP mail list and Ubuntu forums but all has been quiet.</div>
<div><br></div><div>So I trashed that Idea because I spent too much time on it, and there is always another way to skin a cat. So I started down the OpenVPN route and use the PAM plugin they provide since I know my PAM and Radius are happy together. I got a test server up authenticating via certs. "Great!!!" Time to get it authenticating with the openvpn-pam plugin. Well not so fast: When I enable the PAM plugin in the OpenVPN server and try to start it, OpenVPN throws a segfault <span class="Apple-style-span" style="font-family: Verdana, Arial, Tahoma; font-size: 12px; "> kernel: [3725586.167177] openvpn[28364]: segfault at 0 ip 00007fd6e5e38fb4 sp 00007fff434f18f0 error 4 in openvpn-auth-pam.so[7fd6e5e38000+3000] Ugggg I can't win for loosing. Google turns up no joy on Segfaults with </span><span class="Apple-style-span" style="font-family: Verdana, Arial, Tahoma; font-size: 12px; ">openvpn-auth-pam.so. So I'm back to square one.</span></div>

I'm pretty much at my wits end with this one, and stuck. Just not sure what to try next. Does anyone have a working PPTPD via Radius config they would like to share? I might be missing something, but I have been over things a couple two three times the past couple of days. Here is my original post about my PPTPD issue. </span><a href="http://ubuntuforums.org/showthread.php?t=1517219">http://ubuntuforums.org/showthread.php?t=1517219</a> again any help at this point and time would be GREAT.</div>
