Cookie check in index.php mis-placed?

[rosali]

I experienced problems caused by the cookie check in line 84 of index.php when trying to login from an external form on a different domain. The external app where I try to get an integrated login does not use cookies.

in my case the cookie check only works when i set the cookie with

$_COOKIE['roundcube_sessid'] = session_id();

in the startup hook

i have tested with the autologin plugin based on autologon sample plugin otherwise roundcube tell me thats my browser cookies not akzepted.

Fixing this would mean that regular logins will just fail without this specific warning if one really has cookies disabled.

The problem with external logins can be solved using the 'authenticate' plugin hook. Check for referrer and disable cookiecheck.
