Given I know how to set up a folder share on Windows 10 to allow [Everyone|Authenticated Users|specified users] access to a network share.
I recently tried to define share access using a local group, "Users". This is not the obsolete and useless "Homegroup" feature; in the permissions dialog, where you can add users, enter the name of a local user group and this will be accepted. The members of this group are local accounts, but linked to Microsoft logins, for password synchronization.
I found that users in this group were not able to access the share from a remote client, they would get an error message that their password is not right. In the host's event log I find an entry with ID 4625 (unknown user or bad password). This was tried through the file explorer as well as the net command. If tried on the host system itself from an account in the user group the attempt to access the share is successful though, the user can access the network path and also access files in it.
If I explicitly add the user's name to the share, remote access works for the share, too, but I would like to use groups here, as there will be multiple shares to be defined with different access levels to each group.
I am quite sure that in the past using local groups worked as expected, and somewhere with the latest Windows updates this feature was botched, probably when they introduced Microsoft live logins as default.
I had a chat with Microsoft second level support but that was little satisfying. All they were able to provide was a page on how to share folders with other users and no mention of groups.
If you have a similar setup functional, could you provide missing steps?
