In my testing, it isn’t. But if authentication fails IIS will fall back to anonymous (if it is allowed). That isn’t Duplicati requesting anonymous access, but rather IIS falling back to anonymous I believe.
Okay. I can’t see such a behaviour when using a net use command to mount the webdav directory, but i don’t know - maybe.
But maybe it was at some point during your testing?
Good to keep this in mind: But i can exclude that. I publish the authoring rules by using a script. No such config was rolled out.
That’s quite large for dblock sizes. 50MB works fine for most people, and remember it doesn’t mean you can’t back up source files that are >50MB. Source files are broken into chunks and repackaged before uploading. Even if block size is 50MB you can still back up files that are gigabytes in size.
I understand that: But if someone is using a WebDAV directory, he probably want to use generally bigger files. I have to change it anyways.
Let’s make sure we are talking about the same thing. ‘Anonymous Authentication’ piece of IIS can stay enabled, and should be for most web servers. I was talking about Anonymous WebDAV authoring - I would not leave that enabled, and from your screen shot it doesn’t appear to be.
Okay, the authoring was never enabled for anonymous users. I always talked about the anonymous authentication of IIS itself. When disabling it, the username of the WebDAV client becomes visible in the logfile, otherwise not. I can swear i did not change the setting yesterday but became unsure after i saw it. I remember, i had similar issues that went away without config change on the server side (i thought).
Remember with IIS you can enable/disable options and tune them at almost any level: Site level or various directory levels. Make sure you are only tuning them in the right spots and that you’re consistent about it.
I’m doing that. I only work on site level. I publish configs only by command line. Validate every change. I’m normaly very precise at it.
Here is something strange. Please take into account, that Duplicati is not really working as expected.
I will proceed to test other tools and the previous Duplicati version.
I would like to thank you a lot for your time. In case you are one of the dev’s @duplicati, i will be always here to help out with closer work together, in case your time allows and/or interested.
Cheers
