While Nextcloud is often used in companies to replace aging ‘shared folder’ solutions like a Windows Network Drive, the sharing model modern Dropbox-like solutions use is very different. Rather than a single, fixed folder structure available to all users and tightly controlled by IT, users have their own view on their data and can share files and folders at will with others, who will receive shared files in their home file view.
As this release brings so many improvements, we’ve written 4 other blogs with more details about the main features:
A major difference between the folder tree ruled by system administrators and the user-centric view is the use of access control lists (ACL’s) in the ‘old’ world. These allow an admin to share a folder with all users while changing the access rights on sub folders and folders in those folders and so on. This makes it possible to have read-only access to a top folder, write access to a sub folder, read-only to a folder in there again and so on. Nextcloud can give users access to a Windows Network Drive as external storage and respects these ACL’s, but does not otherwise expose them for manipulation.
Nextcloud 16 introduces support for ACL’s in group folders. System administrators can set, on every file and (sub)folder in a group share, specific access rights. These are inherited by default, so a ‘no write access’ for a specific user or group will apply to all files and sub folders, unless overridden again by the system administrator.
Available for configuration are Read, Write, Create, Delete and Share permissions, each of which can be set to ‘inherit’, ‘allow’ or ‘deny’ for each user or group for each file and (sub)folder in a group share.
How it works
To set up a group folder with ACL’s, the administrator enables the Group Folders app, creates a group folder and selects the groups who should have access to it. Make sure the admin who has to set up the permissions is included. Then, enable the ‘advanced permissions’ setting.
In the Files app, go to the group folder and look at the sharing view. There will be a group folder permissions view, where you can specify permissions. Use the ‘Add advanced permission rule’ button to add a rule.
You now pick from a list of all groups and users who have access to the group folder and can then set the fine-grained permissions. Note that ‘inherit’ is default, and by removing the rule with the ‘x’ on the right you can return to the permissions inherited from the parent folder.
Users can see what their rights are, but not modify them.
Today, US-based file sync & share vendor Kiteworks announced their acquisition of ownCloud and Dracoon. Kiteworks points out that their customers now have access to their file-sharing application. It is to be expected they will not maintain 3 similar products, but customers will have to migrate to the US firms’ platform or look for another […]
As part of Schleswig-Holstein's state digitization strategy, the state chancellery has announced they will work with Nextcloud to develop AI for working with government documents. This comes just after we announced the first private AI assistant last weekend with Hub 6. The German state already uses Nextcloud and their AI strategy aligns with our work on ethical, local AI technologies.
Over the last year, AI has become a popular topic. Some is hype, some is substance. Some is good, some is bad. We want to give you the good, not the bad, and ignore the hype! AI has a ton of opportunity – but also risk. So we put you in control – off by […]
The serious security flaws in ownCloud (now owned by Kiteworks) do NOT affect Nextcloud. We have strict security processes in place, and do not ship test data from libraries that can cause security breaches.
Minor Nextcloud updates are released, as well as an update to the desktop client.
As always, minor releases include stability and security improvements that are designed to be a safe and quick upgrade.
