WebDAV with ZCS 5.0.2 and Windows XP

[rwjblue]

I am trying to access the WebDAV service on our newly upgraded server. I thought that I should be able to create a Web Folder in Windows XP like I normally would with WebDAV. When I tell the add network place wizard to use http://servername/dav/username/briefcase/ I get an error that says:

The folder you entered does not appear to be valid. Please choose another.

When I access the path from inside IE (telling it to open the path as a Web Folder) all I see is what looks like the text of a WebDAV session. Like the following:

I am going to try an external WebDAV client (possibly NetDrive) next to see if that fixes the issue, but it definitely would be nice to be able to use without installing any software.

Any idea what can be done to get it working without additional software?

Thanks,

Same problem with Vista here.

Same problem and also no solution!

Try

I have tried:

https://servername/dav/username
https://servername/dav/username/
https://servername/dav/username/briefcase
https://servername/dav/username/briefcase/

All of these have the same result.

Well, I would suggest only trying the PROPFind url, which is /dav/username

Others will yeild errors (probably).

Next, look for errors while connecting in the /opt/zimbra/log/zmmailboxd.out and /opt/zimbra/log/mailbox.log

I'm pretty sure the errors revolve around the httpS. I have tried to resolve this in the past, but basically Windows just cannot seem to connect correctly to secure HTTP servers through WebDAV.

Some more info here:
Using WebDAV for documents as Windows network share - Open-Xchange

I also believe having MS Office installed can change it, since Office does something to the Web Folders as well.

I just tried this using https://servername/dav/username under Leopard and it worked properly. So at this point I would probably agree that there is something wrong with the way Win XP handles WebDAV. I am still unsure as to whether the problem is with the fact that I am trying to use HTTPS instead of HTTP in Windows or that WebDAV simply does not work properly in Windows at all.

Has anyone gotten WebDAV to work under Windows XP or Vista with either HTTP or HTTPS?

Thanks,

Hi!

I've had the same issues with WebDav on WinXP. It worked with http but not with https - the same

The folder you entered does not appear to be valid.  Please choose another.

I tried the solution mentioned on the OpenXchange-page, in esssence search for "webfldrs.msi" in your windows folder, run it, choose the correct settings and reinstall webfolders in your system. Now https works for me in WinXP!

The problem is that you still need to install something on the majority of systems and for me I like that I can mount the briefcase as X: in Netdrive.

This problem exists because Microsoft does not correctly implement DAV (MS WebFolders). They have violated the RFC of a protocol that they originally helped draft! I've had the same problem with Apache/mod_dav before and tracked it down to how Windows issues the authentication strings. Really, the only problem is that MS decided that they want to make all authentication to DAV sources in the form of:

DOMAIN\user

Also, MS tends to transform URLs to UNCs (\\server\share), which you can get around..

Out-of-the-box compatibility with Microsoft's buggy "WebFolders" implementation of DAV would be a *huge* thing for Zimbra. Get ready to throw out your SharePoint servers! The only other companies I know that have successfully done this are:

Xythos:
- Online Document Management - Enterprise Content Management - Online File Storage - Secure Document Collaboration - Document Management - Records Management - Document Workflow - Document Imaging

South River Technologies:
- FTP Server, FTP Client, Managed File Transfer, and WebDAV Collaboration Software

There is a reasonably easy way to make apache/mod_dav compatible with XP using another module mod_encoding:

BTW: There is an existing bug report to do this (24278): Bug 24278 - WebDav Is Broken
