Unstalling since we're on Horde 4 now and the Kolab modules are being 
rewritten.

This is only true if the Cyrus server actually supports anonymous 
login which it does not in most cases. So this fix won't help in most 
cases.

maybe you add the lines



+       if (!$login) {

+           $login = 'anonymous';

+       }



to the code as described below as it lets the initial login screen 
appear much quicker (on my kolab-2.1 debian/lenny system).

Marking as stalled since I would like to restructure the Horde::Kolab 
module before looking into this. The restructuring requires Horde 4 so 
this will still take some time.



If someone submits a patch to make this work earlier I'll definitely 
take a look :)

hi gunnar,

the delay before the login page appears is gone when i put this at the 
beginning of the connect() method in lib/Horde/Kolab/IMAP/pear.php (i 
still have an unpatch libc-client):



<snip>

     function connect($login, $password, $tls = false)

     {

+       if (!$login) {

+           $login = 'anonymous';

+       }



         $this->_signature = $this->_server . '|' . $this->_port . 
"|$login|$password|$tls";

     [...]

</snip>



i still cannot show a shared calendar that has "anonymous read" in the 
kolab-webadmin interface set... but getting rid of the delay is 
already pretty nice!!!



mike

You can certainly make parts of horde available to unauthenticated 
users. I never tried it myself but I guess you could have a public 
calendar. So I assume that you somehow configured things in a way that 
the apps try to display something to a user that did not login yet.



I do actually believe that the log entries you posted are related to 
the error since having the three apps (mnemo, nag, kronolith) call 
listShares() before the user logged in probably corresponds with the 
three errors you see on the screen.



Of course these errors shouldn't be there so it would be good if you 
can determine the sequence of events that leads to the error. Try to 
dump a traceback right before listShares is called in nag/lib/Nag.php 
for example.

hi,

i am actually not sure any more if the logfile entries i posted really 
relate to the php-error on the login page. i will explain the whole 
issue i observe during the login process further below.
ISSUE 1 (probably needs a separate ticket):

-------------------------------------------------

when i visit my horde website i observe quite a delay loading the page 
(you can currently also view the php-error there that is described 
below):

https://mail.das-netzwerkteam.de/mailxchange



this delay is probably related to some horde functions trying to 
retrieve information from the KOLAB IMAP server, but the server 
replies with an auth failure ("badlogin: localhost [127.0.0.1] 
plaintext  SASL(-1): generic failure: All-whitespace username.").



however, i do not really have a clue what horde is looking for on the 
imap server. is it possible to view IMAP data (e.g. a totally public 
calendar) prior to user login???



ISSUE 2:

----------

after a little while the login page appears. without the change 
described in this bug ticket i get the reported php-error. i currently 
wonder if this bug is actually related to my personal fix of ticket 
6048... ($this->_shareMap[$cid] does not get set by getShareById()).



i will check with CVS version...



best,

mike

I'm probably being dumb on this one but I still fail to see the connection.



In your original message you propose to fix the getShares() function 
within Share.php.  You associated that with a few lines of log 
messages that all point to locations where the listShares() function 
gets called. This seems to make sense to me because listShares() 
actually calls getShares() with the result from _listShares().



Now you say the wakeup() call is causing the problem but I fail to see 
the connection to getShares(). Can you provide the complete sequence 
of function calls? Does the error occur when the login page is shown 
and you did not enter any values yet? Or does it occur when you 
entered user and pass and the system tries to auth against imap?

hi gunnar,

note: i am talking about pre-login stage. at this point IMAP auth 
fails in __wakeup in class Horde_share_kolab.



_listShares() / Share/kolab.php is not reached without authentication.



mike

Hm, I'm not certain about this one.



_shareMap is initialized as empty array in the class. So if you call 
getShares with a set of ids, they should end up in $missing_ids.



Now getShares() will try to fetch these missing shares. If it fails 
there, since the share does not exist, it will return a PEAR error.



So I don't think checking for an empty shareMap is really necessary.



From what you post I get the impression that the _listShare() 
function within Share/kolab.php is the culprit in this case. Can you 
check what this function is returning when the sequence 
listTaskLists() -> listShares() -> _listShares() (nag/lib/Nag.php -> 
Share.php -> Share/kolab.php) gets executed? Thanks!

i am using kolab-2.1 (debian unstable) and horde-webmail-1.1rc1



some more php error sedation for the login paged caused by 
non-authenticated IMAP access attempts:



Warning: Illegal offset type in isset or empty in 
/usr/local/share/_horde-versions_/horde-webmail-1.1-rc1-netzwerkteam/lib/Horde/Share.php on line

the error is occurs thrice on every login page, here are the relating 
syslog entries of the occurring errors:
