Hi,

>Can you see your data if you type the webdav url in some browser?
Yes, I can connect to the webdav URL with my browser. It’s read-only, of course, but directories and files are chown, navigation is correct. It ask me for my username and password fine.

>Or you get permission denied only if you try to create a new folder? (You can test it with windows web folders)
I connect with success to the webdav folder by windows web folder. Navigate fine. But when I want to create a folder, it says “Error 0x80070780 : System can not acces to the file”. Idem if I try to copy a file. Everythings goes fine of I do it in the web interface of ownCloud (data are stored in a folder outside the web folder – but I’ve tried to place it in the web folder and the problem was here anyway).

>Check the apache configs and htaccess regarding to allow/deny/satisfy configurations.

Here, you’ll find the virtual host config (standard for directadmin – username and real domain are replaced). I see nothing particular, but perhaps my eyes are not enough open today ;-) I know that suPHP don’t want folder writable by group, is it possible that windows sync client ask sabreDAV to do that ? But there’s no alert in suPHP log, like I found usually.

>Some Limit configurations in apache?
What kind of limit must I search please ? I’ve read all apache conf files (with direcadmin, conf file is split in many files, by theme). Some of them have limit statements but I’ve not seen something like that seems to be relative at my owncloud vhost.

>Do you have something like mod_security?
No I have not this module.

Here the list of modules, obtain by httpd –l (dav modules are not actives, like you see in the vhost conf file):
Compiled in modules:
  core.c
  mod_authn_file.c
  mod_authn_default.c

Thank you for your help. I understand my problem is particular (but common at my too directadmin servers, perhaps all directadmin install). I appreciate the time you spend trying to find a solution.

Hi,

It's not the owncloud problem, something is wrong with apache configuration or htaccess. I assume that your php configuration is clean if you can reach the owncloud web interface.

Can you see your data if you type the webdav url in some browser? Or you get permission denied only if you try to create a new folder? (You can test it with windows web folders)
Check the apache configs and htaccess regarding to allow/deny/satisfy configurations. Do you have something like mod_security? Some Limit configurations in apache?

Hi,

On my problem, I investigate more.

Access log is (when clicking on "create" button in the windows client 1.0.2" :
109.190.0.101<http://109.190.0.101> - - [31/May/2012:11:20:51 +0200] "GET /files/webdav.php/PCClenet HTTP/1.1" 404 710 "-" "mirall-1.0.2"
109.190.0.101<http://109.190.0.101> - - [31/May/2012:11:22:33 +0200] "MKCOL /files/webdav.php/PCClenet HTTP/1.1" 403 1405 "-" "mirall-1.0.2"

Then error log is
[Thu May 31 11:22:33 2012] [error] [client 109.190.0.101<http://109.190.0.101>] client denied by server configuration: /home/myuser/domains/*******.com/public_html/mutu101/files/webdav.php
[Thu May 31 11:22:33 2012] [error] [client 109.190.0.101<http://109.190.0.101>] client denied by server configuration: /home/myuser/domains/*******.com/public_html/mutu101/files/webdav.php

I've

searched about Dav module. They are present in my Apache, but not activated (this need a special directive in my vhost conf file, not used in my case)

I've searched about problem in the apache vhost conf file, but it seems normal, without special deny entry.

I've searched about .htaccess. I've seen that authorization directive may cause pb with suPHP. But applying a workaround found here ( http://bugs.owncloud.org/thebuggenie/owncloud/issues/oc-164 ) does nothing.

I've searched about an suPHP problem. I can't investigate more in that case because I haven't any help in log file about wich PHP file really send the 403 response. I've seen many reasons in scripts that could generate a 403 return header.

To go further : Is it possible to increase log level of ownCloud to get very verbose log, even for webdav connection (like the client do) ?

Is there ant

 oher

way to investigate more ?

Gwenaël MOREAU

Hi,

strange.
Can you try to to uninstall the apache webdav support completely?
Do you see more information in the apache error log?

 After

installing the sync client, when creating sync profile, a step is dedicated to configure a directory on the owncloud server to sync. The client provide a button to create the directory. After creation, it says everythings goes fine but finaly re-ask for creating the directory. In the server log, a line with "client denied by server configuration:" appears.
