Sharing via Document-App does not work when using LDAP

[zeus86]

The sharing via the Document-App does not work when using LDAP.
The only thing you can do instead is sharing the document via the "files"-app with write permission, and then have the users to move the file in their "files"-view into the designated "documents"-folder.
After that, the status of with which users the file is shared is also correct then, even in the documents-app.
This seems only to happen when using LDAP, but affects all users then, also the admin-user.

This issue seems to be related to this particular case .

Steps to reproduce

1. Use Document-App to create a new document and type some characters in
2. click on share
3. choose users and/or groups

Expected behaviour

document is shared between selected users/groups and appears in the dedicated, configured Documents-Folder at everyone this is shared with

Actual behaviour

share-overlay is in "loading" state, and never finishes

while reading some of the other issues here regarding sharing, i shall say that this seems not to be the exact same error some others here ran into. for example i do not get an "error popup" or something like that, the loading-circle just keeps spinning.
