Receiver of a share from a external mount point cannot see the shared files

[jvillafanez]

Steps to reproduce

1. Setup an admin mount point with a specific configuration, only for the admin. Make sure sharing is enabled for the mount point
2. Setup the same mount point as personal for the admin. The mount point configuration must be the same as the admin one. Sharing must be disabled for this mount
3. Share a file from the mount point to another user
4. Login with the other user's account

Expected behaviour

Shared file should show up

Actual behaviour

Shared file is missing. The user account can't access to the shared file.

Server configuration

Operating system: ubuntu 16.04

Web server: apache 2.4.7

Database: mysql

PHP version: 7.0

ownCloud version: master (Aug, 2th 721b36d)

Updated from an older ownCloud or fresh install: fresh install

Are you using external storage, if yes which one: reproducible with any external storage

Are you using encryption: no

As a workaround, you'll need to enabled / disable sharing for both mounts.

Hmm, could it be related to the fact that they both share the same storage string id ? But they should be different mount entries in the mount config tables.

One mount point should only be possible for one owner/user one time. For me, for now its sufficient to document that, if easy or when this is hit by users/customers we maybe need to forbid it. Or is there a good user story why somebody would want to do that?

[PVince81]

@hodyroff currently system-wide mount points can be assigned to multiple users/groups (field "applicable") by an admin. Such mount points can only be created by admins. So this is a supported case.

Now with the case above, I think the proper way would be that the admin adds the user in the "applicable" field to give the user access to that share instead of letting the user add a new mount for themselves.

It seems the admin configuration is overlapped with the personal one, so what is used is whatever the personal configuration has. Since the personal configuration had the sharing disabled that would explain why the shared files are missing.
If we switch the sharing configuration so the personal mount has sharing enabled but the admin mount has it disabled, the personal mount will take precedence, so sharing will be enabled and the shared files will appear.

I think this mount overlapping has been discussed already. This seems another issue caused by that mount overlapping.

Ah, it wasn't clear to me that both mounts use the exact same mount point name... This is not good practice... and also an unsolvable bug (unsolvable without tearing up a hole in this messy mount system): #10511

I'd close this in favor of #10511 then...

The mount point name is different, but the configuration is the same in both.

[PVince81]

Ok then it's a different issue. The end user should see both mount points, one with sharing enabled and one without

Due to it is not a very common configuration let's set a lower priority
