This looks related in some way to bug 48576. Mod Negotiation is loaded, but Multiviews has been turned off. I tried -MultiViews as well as removing all MultiViews options from the configuration. The problem goes away if mod Negotiation is not loaded. Create a file via Webdav with an extenstion. "foo.zip". Now try and create a directory with the root name of the file: "foo". The directory creation will fail with a "400 Bad Request" Internal to the WebDav code it thinks that "foo" already exists as an object during the "mkcol" command.
I can't reproduce that. Is there anything relevant in the errorlog if you set loglevel to debug? Can you post a simple example config with which this bug is reproducible?
I also faced such problem. The following error log is written in the error log file: Could not fetch resource information. [400, #0] The URL contains extraneous path components. The resource could not be identified. [400, #0] The configuration that reproduce problem: Alias /user13 "/home/davusers/user13" <Directory "/home/davusers/user13"> DAV On ForceType text/plain DAVSATMaxAreaSize 8192000 // This directive comes when installing 3-rd party patch for quota management Options Indexes MultiViews AuthType Basic AuthName "Test Account for Basic autentication" AuthUserFile /etc/apache2/sites-enabled/.password Require valid-user AllowOverride None Order allow,deny allow from all DirectorySlash ON </Directory> To reproduce problem firstly create aaa.txt file then try to create aaa directory using MKCOL /user13/aaa/ HTTP/1.1 Apache server version: Server Version: Apache/2.2.16 (Debian) DAV/2 PHP/5.3.3-7+squeeze13 with Suhosin-Patch mod_ssl/2.2.16 OpenSSL/0.9.8o System: Debian 6.0.5 x86_64 When I remove mod negotiation as described below, the problem solves.
