Unable to connect from AnyConnect 3.0 and 3.1 Windows Clients to ocserv 0.2.4 and git head

[thomas at glanzmann.de (Thomas Glanzmann)]

Hello,
I compiled ocserv git head and 0.2.4 on Debian Wheezy using the gnutls
library from backports, I configured it and I'm able to connect using the
Android AnyConenct Client without any issue, however I'm not able to
connect using AnyConenct 3.0 and 3.1 from a Windows 7 PC. My config is:

                </HostEntry>
        </ServerList>
</AnyConnectProfile>

My server cert has the certificate itself and the intermediate certificate in
it. I tried to use a wildcard and a certificate with only one CN. Here
is the debug log:

http://pbot.rmdir.de/PhPvw1B5B14p5be5FCCepw

I tried with and without DH. The debug log is without DH.

When I connect using Cisco AnyConnect on Windows, I'm asked for a username and
a password. Once I type them in it prompts me again for username. I made sure
than I open all ports in both of my firewalls.

I would appreciate if someone could tell me what I'm doing wrong.

Cheers,
