Nextcloud 13: New Users/Groups do not appear in combobox if I try to share a folder

Dear All, this is the issue I face in the new nextcloud 13:

Nextcloud version :
Operating system and version : Ubuntu 16.04
Apache or nginx version : Apache/2.4.18 (Ubuntu)
PHP version : 7.0.25-0ubuntu0.16.04.1

The issue you are facing:
I added new users and new groups. After that I created a new folder and wanted to share this with the users. In the combobox of the share configuration the new users and groups are not found/displayed.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Create new user (and group)
  2. try to share folder or file with new user/group

The output of your Nextcloud log in Admin > Logging:

nothing specific

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

$CONFIG = array (
  'instanceid' => 'xxx',
  'passwordsalt' => 'xxx',
  'secret' => 'xxx',
  'trusted_domains' => 
  array (
    0 => 'xxx',
    1 => 'yyy',

The output of your Apache/nginx/system log in /var/log/____:

nothing fitting. 

Best regards


remains the same after update to NC 13.0.1

PS: If I login with the new user id, then I only see the new users in the comboboxes.
