I’ve just upgraded my ‘home’ egw installation, and tried to revamp our
family calendar.

My egw installation is really simple, on a debian etch box, using only
an SSL-enabled virtualhost on apache2/php5.

I’ve tried to switch from syncevolution (that works, but sometime break
something and when break, it need many work to fix it…) to GroupDAV,
with some trouble.

in addessbook i’ve defined an addressbook of type WebDAV, with an
URL of:
```
 https://myserver/groupdav.php/addressbook/
```

in apache logs i found a bounch of:

    aldo - anna [30/May/2009:23:02:44 +0200] "PROPFIND /groupdav.php/addressbook/%20/ HTTP/1.1" 207 87
    aldo - anna [30/May/2009:23:02:45 +0200] "PROPFIND /groupdav.php/addressbook/%20/ HTTP/1.1" 207 87

and in error logs:

    [Sat May 30 23:01:56 2009] [error] [client 192.168.1.16] Unrecogniced GroupDAV client: HTTP_USER_AGENT='Evolution/2.2

6.1’!
[Sat May 30 23:02:45 2009] [error] [client 192.168.1.16] PHP Warning: Invalid argument supplied for foreach() in /usr
/share/egroupware/egw-pear/HTTP/WebDAV/Server.php on line 590
[Sat May 30 23:02:45 2009] [error] [client 192.168.1.16] PHP Warning: Invalid argument supplied for foreach() in /usr
/share/egroupware/egw-pear/HTTP/WebDAV/Server.php on line 700

and addressbook are empty (in egw the anna’s addressbook are not) and i
cannot add new entry.

calendard works, i can see all appointments, i can add one, i can
alter an appointment but i cannot delete one. If i try to delete i
can see on access log:
```
 aldo - anna [30/May/2009:23:09:22 +0200] "DELETE /groupdav.php/calendar/5669.ics HTTP/1.1" 412 -
```

no error at all in error log; note that on both case Evolution return a
unmeaningful generic error.

I’ve triead to delete the appointment in egroupware with user anna, and
works flawlessy (and clearly was deleted also in evolution).

Another note, and i don’t know if this is an evolution or egw bug: i’ve
tried to setup two CalDAV calendars to the same server (with two user,
anna and gaio), and i’ve got the same calendar (the first one) duped; i
can see that authentication work, data are collected but i think that
evo do some mockups with temporary files or egw send the same data to
both ‘account’.

many thanks.

%20 means you put a space (’ ') behind the url.

and in error logs:

412 HTTP code means “Precondition failed”: you client send an etag as
HTTP_IF_MATCH header, which does NOT match the current etag.
etag’s are the version of an entry, the client basicly said delete it,
IF it’s not changed and 412 from the server tells the client it has changed.

no error at all in error log; note that on both case Evolution return a

I dont know Evolution, there’s a similar problem with lightning: the
password store, stores one password per url, so you need to have
different url’s or put the password in the url, eg:

http://user:password@domain.com/egroupware/groupdav.php/calendar/

Better would be to use:

http://domain.com/egroupware/groupdav.php/user/calendar/

I included that syntax in the initial implementation, but never tested
it. It would allow to look into an other users calendar (ACL permitting)
with YOUR credentials. Therefore no need to store two credentials or
share your password with an other user.

Mandi! Ralf Becker
In chel dì si favelave…

    aldo - anna [30/May/2009:23:02:45 +0200] "PROPFIND /groupdav.php/addressbook/%20/ HTTP/1.1" 207 87

%20 means you put a space (’ ') behind the url.

AARRGGH!!!

    aldo - anna [30/May/2009:23:09:22 +0200] "DELETE /groupdav.php/calendar/5669.ics HTTP/1.1" 412 -
412 HTTP code means “Precondition failed”: you client send an etag as
HTTP_IF_MATCH header, which does NOT match the current etag.
etag’s are the version of an entry, the client basicly said delete it,
IF it’s not changed and 412 from the server tells the client it has changed.

Ahem, sorry but really i’ve not understood… it is an evolution
trouble or an egw one?

Anyway, my wife say me there’s also some trouble with recurring events,
seems there’s no way to insert one.

Better would be to use:
http://domain.com/egroupware/groupdav.php/user/calendar/

aldo - anna [10/Jul/2009:00:50:08 +0200] "OPTIONS /groupdav.php/gaio/calendar/ HTTP/1.1" 200 -

but does nothing, calendar are empty, and anna have at least read right
(via the group ‘casa’) to the gaio’s calendar.

Many thanks!!!

Ok, just upgraded to 1.6.002 and now i can insert recurring event and
delete events, the only things i can’t to is delete alla events of a
recursion, i have to delete the singular events.

[multiple url and access by another user]

Better would be to use:
http://domain.com/egroupware/groupdav.php/user/calendar/
aldo - anna [10/Jul/2009:00:50:08 +0200] “OPTIONS /groupdav.php/gaio/calendar/ HTTP/1.1” 200 -
but does nothing, calendar are empty, and anna have at least read right
(via the group ‘casa’) to the gaio’s calendar.

I’ve double checked and in egw anna can see the ‘gaio’ caneldar, but if
i create a new calendar with the url above, the calendar are empty,
with no error in logs…

Again, many thanks.
