Alfresco WebDav server not usable with files_external

[ebogaard]

Steps to reproduce

1. Add Alfresco 5.x as webdav server to your personal account as external webdav-server
2. Try to access the External storage
3. See the error on screen
4. Check the webserver on the Alfresco server and see a number of 401's and 207's - see log at the bottom of this issue description.

If needed: please let me know if you need access to an Alfresco server to try the webdav-connection against

Expected behaviour

I expect to see the files and folders available

No files, just an error on screen:

@icewind1991 any idea about that thing? Is it known for problems/to work?

[heaven73]

same behaviour on a webdav share on IIS tried to connect to as external storage on a fresh installation. The Webdav share can be reached by various davclients like cyberduck

[stunivention]

Similar to the behaviour I've seen while trying to add an OpenXchange Drive via webdav as external storage in Nextcloud 11.0.1.. Folders are partly visible, but no files. Uploaded files are not visible in Nextcloud, but in OX Drive.

This Alfresco issue may be related: https://issues.alfresco.com/jira/browse/MNT-9939?focusedCommentId=288101&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-288101

When I try to reproduce the testing with litmus it hence fails at 23. lock_shared (412 Precondition Failed). Alfresco passes all other tests.

[pieter-groeneweg]

Same applies to FTP and CIFS if that is enabled in Alfresco... I also cannot use that. It just won't work as expected.

For me somehow the only way to add an Alfresco site through webdav is to mount an alfresco webdav location as local folder. Then choose local folder as external storage.

As similar happens when trying to add a remote Alfresco location as local folder in Windows Explorer for example, I guess it is an Alfresco thing, not so much Nextcloud (nor Windows Explorer)

[noci2012]

Using a local storage bypass for alfresco defeats the pupose of using / authorizing people within Alfresco.
Or having specific mounts per [ "group" of ] users within Alfresco.

[pieter-groeneweg]

Unless you have some sso installed.. I can completely understand why one would want to use a bypass.
Though Alfresco can have great workflows and using Activiti BPM can have added value, sharing is really lowsy. The methods of sharing files and folders within Alfresco is useless for a lot of users. One can only share full sites with users, no public sharing, no expiry dates, no....

There is very good reasons to bypass.
But then again... asmentioned the CIFS/SMP/FTP in Alfresco doesn't even work properly.

[noci2012]

Nextcloud offers to remember per user passwords for a remote service
No SSO needed, or available.
NextCloud 15.0.4 still cannot show content of folders using WebDav.

You can use http://docs.alfresco.com/community/tasks/deploy-docker-compose.html to setup alfresco (without download around 5 minutes).

I can mount with nautilus but not nextcloud. Above is the response from alfresco.
