The university of Lausanne recently introduced 2-factor authentication for its VPN, and since then my working openconnect setup is failing with this error :

Unknown form (name 'form1', id '(null)')
Dumping unknown HTML form:
<form name="form1" action="/idp/profile/SAML2/Redirect/SSO?execution=e1s1" method="post">
        <input name="shib_idp_ls_exception.shib_idp_session_ss" type="hidden">
        <input name="shib_idp_ls_success.shib_idp_session_ss" type="hidden" value="false">
        <input name="shib_idp_ls_value.shib_idp_session_ss" type="hidden">
        <input name="shib_idp_ls_exception.shib_idp_persistent_ss" type="hidden">
        <input name="shib_idp_ls_success.shib_idp_persistent_ss" type="hidden" value="false">
        <input name="shib_idp_ls_value.shib_idp_persistent_ss" type="hidden">
    <input name="shib_idp_ls_supported" type="hidden">
    <input name="_eventId_proceed" type="hidden">
        <input type="submit" value="Continue">
</form>Failed to complete authentication

The authentication seems to now be "provided" through the eduid infrastructure of switch.ch through a shibboleth framework, if that rings a bell to anyone...

Should I just try to add a recognition for this form in the code and see what happens ?

Thanks for your help, and kind regards,
