I want to make a full test of ezpublish and I didn't managed to make webdav feature working after almost 3 days.

My current configuration is Apache 2.2.x with PHP 4.4.2 runing as module and postgres 8.1 (there are still charset problems with ez+mysql)

I'm very upset that the documentation is very incomplete - it's more like a presention and you have to search a lot for finding info. There are LOTS of .htaccess files but none has ever tried to put a good one in documentation and remove the wrong ones.

WebDav module is enabled and webdav log is enabled but there is nothing in the log ($ezhome/var/log/webdav.log).

Did you take a look in the Apache access logs?

If denying access is the default, then I guess you do not have access to webdav.php. The pattern does not include webdav.php:

<FilesMatch "(index\.php|\.(gif|jpe?g|png|css|js|html)|var(.+)storage.pdf(.+)\.pdf)$">
    order allow,deny
    allow from all
</FilesMatch>

The problem is not from the access rights. "Bad Request" it's not a deny.

The only additional info I have right now is that in the apache log I can see:

 [07/Aug/2006:14:59:03 +0300] "OPTIONS / HTTP/1.1" 400 226 "-" "UCI DAV Explorer/0.91 RPT-HTTPClient/0.3-3E"

There is nothing in error log even with <i>LogLevel debug</i>.

Make sure your webserver has write permissions to $ezroot/var/ and anything beneath it.

Enable WebDAV logging in settings/override/webdav.ini.append(.php):

[GeneralSettings]
Logging=enabled

Now take a look in the webdav.log file under var/log and var/<i>siteaccess</i>/log

I've separated the www.mysite.com and webdav.mysite.com in two virtual hosts. The www is working quite well (the site name is 'web') and can be contacted using something like http://www.mysite.com:81/index.php/web/ (root is working too).

About webdav virtual host: (http://webdav.mysite.com:81/ )
- opening in firefox will display a blank page (no error)
- opeing in DAV Explorer gives an error like: ACL Interpreter: "The server does not support DAV at Resource /" logs:

At the same time nothing added to $ez$/var/log/webdav.log
In the mod_rewrite log:

 (2) init rewrite engine with requested uri /
 (3) applying pattern '\.(css|jar|js|html|php)$' to uri '/'
 (2) rewrite '/' -> '/home/httpd/html/ro.intersol/support/webdav.php'
 (2) local path result: /home/httpd/html/ro.intersol/support/webdav.php
 (1) go-ahead with /home/httpd/html/ro.intersol/support/webdav.php [OK]

And in httpd log:

217.156.79.121 - - [07/Aug/2006:20:54:59 +0300] "OPTIONS / HTTP/1.1" 200 - "-" "UCI DAV Explorer/0.91 RPT-HTTPClient/0.3-3E"

Tries with different endings but none seams to work.

Also i've tried to open the url as webfolder with Internet Explorer 7 Beta 3 and apache log shows me several requested files (starting with _cti_inf.html) and strange after this it opens an information message box with no title and no text: options yes/no. If i press no it will cancel the opening and if i press yes i get an 404.

I'm pretty sure that after i finish this endless webdav configuration i will rewrite the webdav install documentation of ez publish :|

Can you show us the exact configuration of your WebDAV virtual host?

We have something like this for Apache 2.0.x:

<VirtualHost IP:PORT>
    DocumentRoot EZROOTDIR

    <Directory EZROOTDIR>
       Options FollowSymlinks
       AllowOverride None
    </Directory>

    <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteRule ^(.*) /webdav.php [L]
    </IfModule>
</VirtualHost>

I've followed all infos and still no result. I've have made some symlinks of all implied config files. You can see them at http://play.intersol.ro/ez/

The url of the webdav should be: http://webdav.intersol.ro:81 and the site at http://support.intersol.ro:81 <i>Don't forget that all ez sites are running on port 81 with apache 2.2.x, php 4.4.x running as module</i>

Too much time spent on this problem. I'm going to try Plone even if I don't like Python. it seams that I could get webdav and OpenDocument support from it too.

Apache 2.2.x? Maybe that could be the problem...

Sorry but i spent too much time on installing "ez publish", there are too many requirements for ancient products. It seams that it <i>could</i> work in a server thats running the 2 years software.

Currently the releases are:
- Apache 2.2 (maybe not supported)
- PHP 5.1 (not supported)
- MySQL 5.1 (not supported or at least you need to recompile the PHP in order to make it work) - but it seamns that is working with lastes PostgreSQL :)

I've spent around 10 days in order to install two copies of PHP make httpd run in two instances one for php4 and one for php5. I don't want to install another copy of apache on my server just to see if it could work.

Maybe I'l try the 4.x version when it will be available IF it will be compatible with the current release of it's requirements.

You're right about PHP 5 :-)

But MySQL 5.1 can be used, but you have to let it use old password hashes. And I wouldn't call Apache 2.0 an ancient product, I think it's still used on most webservers.
