Hi ! I'm trying to connect to our corporate VPN but it only works using --no-xmlpost parameter. My tests with openconnect 7.06 fails if I don't use --no-xmlpost ("Failed to obtain WebVPN cookie"). I also tried the latest commit available in GIT, same problem. It stop working after openconnect 5.03. OC 5.03 works fine without --no-xmlpost. In fact, reading the code I see that it first tries to use xmlpost, then fails, but automatically it tries again setting vpninfo->xmlpost to 0, then work. In openconnect manual page there is a mention if --no-xmlpost is needed it is because there is a bug. So, here we are :) Before write this mail I tried to identify what could be going wrong. I have debugged the cstp_obtain_cookie() function of auth.c file. I believe the problem could be there. More specifically in the Step 2 block. BTW, there is no Step 3 in the source code. It jumps to Step 4 :) Any suggestion what could be my next steps ? Thanks ! Sergio H. M. Durand
