Ah good first step would be to run this on a windows machine first, so you
know for sure the information is correct, and what user/pass/challange you
need to input.

Perhaps gdb or strace might tell you which library is 'the problem' and perhaps
downgrade or upgrade that library, or..

See contrib/cisco/ for a perl script that converts your cisco profile to
an openswan connection. Suse has rpms, but you can also find them on:
Warning: the suse 2.4 kernel (AFAIK) has not applied the natt-patch to
allow IPsec NAT-Traversal. If your linux machine has a real public ip,
this is not an issue, but if you're behind nat, then it is, and you
will have to patch that kernel. You will also need to build the klips
kernel module, though if you rebuild the source rpm, it should build
the openswan-klips package.
I would first try to get it to work on public ip, then try from behind nat.
