Can't unshare Files/Folders shared with Active Directory groups


I’m experiencing a problem with the “unshare” option.

Nextcloud version 12.0.0
Ubuntu Server 16.04 64 bits
PHP 7.0.18


  • “User A” share a folder eg. “Project” with an Active Directory group named “Team”;
  • “User B” belongs to AD group “Team” and the folder “Project” appears in your list;
  • “User B” try “Unshare” this folder but it is not possible. On top of the screen the following message is shown: "
    Error deleting file “Project”.

PS: When the group is a local group, the unsharing works normally.

The output of my Nextcloud log in Admin > Logging:

Hi, just to let you know, I’m having the same problem!
It seems Nextcloud is not always able to recognize group membership for AD groups:
Also in admin->Users , AD groups seems always to be empty, although under “everyone” correct membership is reported for each user.

Nextcloud 12.02
Centos 7
Apache 2.4.6
php 7.1.8

Also moving a shared folder isn’t possible under this circumstances:

  • “User A” share a folder “Project” with an AD group “Team”
  • “User B” is a member of AD group “Team” and the folder “Project” appears in his list
  • “User B” tries moving the folder Project in an other folder e.g. “shares” but this is not possible. The following message is displayed: Could not move “Project”
  • When shared with a local group, moving works as expected

I currently got an issue report and believe the same is true for the general LDAP setup.
