Federation resharing not working as expected

Please use the 👍 reaction to show that you are also in favor of this feature - we are using this information to decide which features to include in upcoming Nextcloud versions. Please don't comment if you have no relevant information to add!

Steps to reproduce

1. Share via federation to user@nextcloudserver.com
2. Uncheck "can reshare"
3. Person receives and accepts share.

Expected behaviour

Tell us what should happen
The person with whom the file or folder was shared should not be able to further share the file or folder. The share link and share options under share should not be visible or grayed out thereby disallowing the person from further sharing the file or folder.

Actual behaviour

Tell us what happens instead
The person shared can select share options like "share link" or share with others via email or federated.

Server configuration

Operating system: Rasperian Stretch

Web server: Nginx

Database: MarionDB

PHP version: 7.0

Nextcloud version: (see Nextcloud admin page) 14

Updated from an older Nextcloud/ownCloud or fresh install: Update from 13.0.6

Where did you install Nextcloud from: Nextcloud servers

Signing status:

Login as admin user into your Nextcloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results here.

List of activated apps:

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

Nextcloud configuration:

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

or 

Insert your config.php content here. 
Make sure to remove all sensitive content such as passwords. (e.g. database password, passwordsalt, secret, smtp password, …)

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

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 Nextcloud 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.

Reproduce the federation-sharing flow described: share with can-reshare disabled, accept the share, and check whether link and sharing options remain available. No files, tests, or entry points are named in the issue, so the relevant sharing and federation implementation must first be located. Done means the recipient cannot reshare the file or folder through links, email, or federation.
