That's expected, if you're not running it as root. Everything worked OK,
but it wasn't able to create and configure the tunnel network device.

But it would have worked from the command line anyway. It was caching
the result of the DNS lookup and using the same IP address every time it
had to make a new connection, so you'd never have seen the original
issue there. It was only when you had the *separate* authentication and
connection stages (for example with the NM GUI, or using openconnect
--authenticate followed by
openconnect -C $COOKIE --servercert $FINGERPRINT $HOST

That shouldn't happen. First thing I'd do is check that you aren't
mixing versions. If you just ran './configure' then it probably installs
to /usr/local, leaving the packaged versions in place? Try adding
--prefix=/usr to the configure command line?

And run 'ldd /usr/libexec/nm-openconnect-auth-dialog' (or wherever
Ubuntu puts it) to check which version of the library it's running.

Was it a segfault in the auth-dialog? Or in openconnect itself when it
tries to connect?

Yes, you have the latest patched version.

No, that shouldn't be necessary.

It'll use GnuTLS if you have it.
