[kronolith] Problem subscribing remote calendars

[Marco Favero]

Hi all,
with horde-webmail edition last version (1.2.1) I try without success to 
subscribe remote calendar (using appropriate username/password).
It seems I have some "errors" relating sessions. This is what happens:

1) I open a remote calendar using this link:
https://myhost.com/rpc.php/kronolith/user1/user1.ics
2) WebDAV request username/password and I download the file with success.

3) Now I want to open *another* calendar:
https://myhost.com/rpc.php/kronolith/user2/user2.ics
2) No username/password request happens, no calendar downloaded, blank 
web page. Into log I see:
2009-01-21T08:52:38.435636+01:00 myhost.com HORDE[20984]: [imp] Login 
success for user1 [10.10.10.10] to {myserver.it:143 [imap/notls]} [pid 
20984 on line 304 of 
"/var/www/html/horde-webmail-1.2.1/imp/lib/Session.php"]

So, I try to open calendar for user2, but the log reports a login for 
user1, which calendar I opened previously!

Do anyone experience this?

If I can't solve this oddity, could you tell me a way to remove from 
kronolith possibility to open remote calendar?

I use memcache session handler. Imp/IMAP login. Follow relevant
