Hello,

I'm using WebDrive to map a drive letter to a WebDAV share running on Subversion with the SVNAutoversioning flag enabled. The Subversion server is running CollabNet Subversion Edge with LDAP authentication.

When trying to connect using WebDrive, I get:

Connecting to site myserver
Connecting to http://myserver/webdrive/
Resolving url myserver to an IP address
Url resolved to IP address 192.168.0.12
Connecting to 192.168.0.12 on port 80
Connected successfully to the server on port 80
Testing directory listing ...
Connecting to 192.168.0.12 on port 80
Connected successfully to the server on port 80

Unable to connect to server, error information below

Error: Socket receive failure (4507)
Operation: Connecting to server
Winsock Error: WSAECONNRESET (10054)

The httpd.conf file running on the server contains the following section:

<Location /webdrive/>
    DAV svn
    SVNParentPath "C:\Program Files\Subversion\data\repositories"
    SVNReposName "My Subversion WebDrive"
    AuthzSVNAccessFile "C:\Program Files\Subversion\data/conf/svn_access_file"
    SVNListParentPath On
    Allow from all
    AuthType Basic
    AuthName "My Subversion Repository"
    AuthBasicProvider csvn-file-users ldap-users
    Require valid-user
    ModMimeUsePathInfo on
    SVNAutoversioning on
</Location>

and in the Apache error_yyyy_mm_dd.log file on the server, I'm seeing this when I try to connect via WebDAV:

Browsing http://myserver/webdrive/ from a web browser is working fine, and I have a similar set-up working perfectly on a different SVN server that isn't running Collabnet but has had Subversion and Apache installed and configured separately.

Any ideas? The python version error might be red herring - I've seen it in a couple of places in the log files and in other scenarios it doesn't appear to be breaking anything...
