Duplicating of users in dropdown list when sharing files and folders

[olegbolden]

Users with numerical usernames (say 5555) have two instances in droplist when sharing files or folders: with email and without it.

Expected behaviour

User wants to share file or folder with some user having numerical username. When he types his name then this name appears once in dropdown list.

Actual behaviour

Name of the user with numerical username on sharing appears twice in dropdown list: with email and without it.

Users with regular usernames have the only instance to select from dropdown list upon object sharing.

GitMate.io thinks possibly related issues are #6491 (Duplicate Shared folders), #8301 (Shared files are duplicated when moved to subdir), #3502 (Duplicated files and folders when moving from one shared folder to another (can reproduce it)), #5336 (Move link sharing into share with user-dropdown), and #10358 (Shared folder only displaying one file).

Eventually got that the second line (user with email) from dropdown list is shown for users with numerical usernames if "Share by email" application is turned on. I wasn't aware of this app. But this second line is not visible for users with regular string names. Though it also seems to be a bug I close this issue because I finally got rid of this duplicating users from dropdown list.

I think this one should be reopened.

On Nextcloud 24.0.5, when "Share by mail" app is enabled, some users are shown twice on the drop down list (a third occurrence can appear if a Talk conversation exists with this user but this seems legit).
The second occurrence of the user can't be clicked to share the file, we're getting error "please enter a valid user".

Maybe the origin of the problem is LDAP account using email address as identifier ? On another instance of Nextcloud that I own, with only regular Nextcloud account, I can't reproduce the problem.

Here is some screenshots :

This user is shown twice, same email address. If I click the second one, it throws error mentioned above. First occurrence of same user work.
Note that the mail icon isn't visible at the right of the dropdown option. Initials are not visible, just a white circle.

On this instance with only regular Nextcloud account (no ldap), all is fine, a user can be pointed by his user account, his mail or the talk conversation. For mail and talk, icons are properly shown.

Any clue ?

Hello I have the same issue. When sharing, there is one user multiply. But in users there is only once. No local users, everybody are from LDAP. NC version 22.2.3.

I again got a user support question about this.

I reopen, this is an UX issue for me.

Users that are not really familiar with nextcloud will click one of the suggestion, and will send a an email invite to actual users of their instance.

And I think it is related to this big redesign :)

Hi, which nc version?

[pierreozoux]

@szaimen it ia last 24.

[szaimen]

Hi, please update to 25.0.7 or better 26.0.2 and report back if it fixes the issue. Thank you!

My goal is to add a label like e.g. 26-feedback to this ticket of an up-to-date major Nextcloud version where the bug could be reproduced. However this is not going to work without your help. So thanks for all your effort!

If you don't manage to reproduce the issue in time and the issue gets closed but you can reproduce the issue afterwards, feel free to create a new bug report with up-to-date information by following this link: https://github.com/nextcloud/server/issues/new?assignees=&labels=bug%2C0.+Needs+triage&template=BUG_REPORT.yml&title=%5BBug%5D%3A+

The issue persists on 26.0.1 (26.0.2 is not available)
