Correction, It isn't when you enter the name, just when you view who the folder is shared with.

@gig13 which users are duplicate?

[gig13]

@DeepDiver1975
Look at the screenshot, It lists the file is shared in "APSC 480 with TREVOR LEWIS (TL33)" -- that users is listed 3 times in the same line.

Then it shows "Shared in APSC 480 2014-15 with JAKE ARMSTRONG (8JEA3)" -- he is listed 3 times in the same line.

1. Why are there 2 lines of the Share
2. Why is each user listed 3 times?

@DeepDiver1975 @PVince81
Any thoughts?

[PVince81]

also @schiesbn

@gig13 did you check whether they have the duplicate oc_storage entries situation ? (local::$datadir/$user additionally to home::$user) Many sharing issues are related to that.

But I must say that this situation is a bit new.

It kind of reminds me of another issue where it would display the users from a group instead of the group name but cannot find the ticket any more.

[PVince81]

Ah, here it is: #12106

@gig13 was the file/folder shared with that user multiple times, like through multiple groups ? If yes, then it could be the same issue.

[gig13]

@PVince81
There was no group sharing whatsoever. Everything was from one user to another (or many other). I will check if the user shared this multiple times -- very possible since they did the upgrade and may have had the initial share, and then after the patch was applied, shared again?

[PVince81]

If there is only one owner and multiple recipients (and no reshares), then this situation shouldn't happen. But who knows... you could check in oc_share whether that user is the recipient multiple times (select * from oc_share where share_with='theusername')

[gig13]

@PVince81
They were only shared once.

[PVince81]

Still happening with 7.0.7 or 8.0.5 ?

@PVince81 -- This has been closed for some time on my side. To re-open if needed.

I can confirm this in 8.0.7 stable.

The situation is as follows:
/FolderA - shared with user1
/FolderA/FolderB - shared with 21 other users

Share dialog for FolderB shows "Shared in FolderA with user1, user1, ..., user1" - user1 is shown 21 times.

There are no duplicated entries in oc_storages for affected users.
There is no group sharing involved of any kind.
Only one entry in oc_share for this share.

Steps to reproduce:

1. Create folder - FolderA
2. Share FolderA with User1
3. Inside FolderA create FolderB
4. Share FolderB with user2, user3, user4 (or more)
5. Open share dialog for FolderB again.
6. Result: Share dialog for FolderB shows "Shared in FolderA with user1, user1, user1" - number of times user1 is displayed depends on how may times FolderB was shared with other users.

Tested on Firefox, Chromium, Opera, different versions, different OS - no difference.
