User groups with spaces or special characters are empty (only on web interface)

[smrecko]

Steps to reproduce

1. On web interface create user grup with space or special character in (for example "Test group" or "TestGroupČŽŠ"
2. Assign any user to that group
3. Click on newly created group so all the users inside this group are listed

Expected behaviour

All users belonging to that group should have been listed in web interface.

Actual behaviour

Group is empty if I look it up over web interface. If I list users over terminal, all users are listed correctly.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.

or 

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Are you using external storage, if yes which one: local/smb/sftp/...
No

Are you using encryption: yes/no
No

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...
Tested on multiple ownCloud servers (only internal users and LDAP) - not working on either

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

Client configuration

Browser:
Tested on Chrome, Firefox, IE (all latest version)

Operating system:
Windows 10

I just tried this on 10.0.10 and it works for me. IMO most issues with "special" group names have been resolved. Issue owncloud-archive/user_management#19 should be fixed in core stable10 by #31109

Please try with 10.0.10 and report back.

[ownclouders]

GitMate.io thinks possibly related issues are #9764 (special characters), #25690 (Empty web interface), #11454 (groups disappear in the Web interface), #28265 (Hi,), and #29158 (Dear Support, ).

Everything is working as expected in 10.3.0. I tested with group name having 2 spaces in both occ and web UI.
