Good morning, everybody. I hope to be able to find a solution on this forum.
I have a problem with permissions on files modifications
My server is configured as follows :
2 users : Paul and Pierre
3 groups : Paul, Pierre and Common
Paul (user) => Paul (group) define as primary group + Common (group) define as secondary group
Pierre (user) => Pierre (group) define as primary group + Common (group) define as secondary group
I have created 3 datasets with the following characteristics:
Paul : user owner: Paul ; group owner: Paul
Pierre : user owner: Pierre ; group owner: Pierre
Commun : user owner:nobody ; group owner:Common
Concerning permissions on datasets:
Paul (dataset) => owner:read - write - execute ; group:read - write - execute
Pierre (dataset) => owner:read - write - execute ; group:read - write - execute
Commun (dataset) => owner:read - write - execute ; group:read - write - execute
Further informations :
The access to the directories is done via a windows share (CIFS).
The access to the directories is done via two PCs, one running under ubuntu and the other under windows 10.
MY PROBLEM :
The user connected on the PC running Ubuntu always takes dominance over the modification of files in the "Common" dataset.
If Paul works on Ubuntu and Pierre works on Windows
If Pierre creates a .txt file in "Common", he is able to modify it. But, if Paul open this file and save a modification, Pierre can no longer modify and save this file.
However, even if Pierre can no longer make changes, he can change the filename or delete the file without any problem.
Worse: I did a test by putting Pierre in a secondary group of Paul and Paul in a secondary group of Peter.
I have the same phenomenon. Pierre (windows) loses the modification permissions on his own dataset as soon as Paul will modify a file on Pierre's dataset !!!
Have you a idea ?
Thank you
