            Bug ID: 133673
           Summary: LibreOffice fails to refresh Locks when using WebDAV
                    with Authorization
           Product: LibreOffice
           Version: 6.4.3.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: Julian.Kalinowski at dataport.de

Description:
When loading a document from a WebDAV Server with Authorization, LibreOffice
first tries to perform every WebDAV HTTP Request without Authorization Header.
As this results in a a 401 Unauthorized Response, LibreOffice tries again with
correctly set Authorization Header (this is for WWW-Authenticate: Negotiate, I
don't know if there are other cases).
Now, requests succeed as expected.
This is shown in webdav-lock-conversation.txt.

However, WebDAV locks need to be refreshed from time to time. As LO does this,
it again tries without Authorization header first, receives 401 Unauthorized -
and gives up.
This is shown in webdav-lockrefresh-conversation.txt (well, there is not much
to show as the conversation just ends after the 401 response).

Expected: LO should try again, just like it does when loading a document.

The conversations were logged with a closed-source WebDAV server. I will try to
reproduce with another one soon.
Also I'm not quite sure what the correct behaviour is when refreshing a lock.
Servers could also accept lock refresh commands without authorization, but
obviously, this one doesn't and the WebDAV RFC does not seem to be specific
about that.

Steps to Reproduce:
1. use webdav server with authorization and locking enabled
2. open odt from webdav server (should lock the file)
3. wait e.g. 180s


Actual Results:
lock is gone as it is not refreshed

Expected Results:
lock should be refreshed correctly


Reproducible: Always


User Profile Reset: Yes
