This seems to be caused by the approach that kwrite uses for saving changes to existing files. Instead of opening the existing file for writing (which you granted the ACL for), it writes the new contents to a temporary file and calls rename() to replace the existing file by the temporary file. For this to succeed, you would need to have write access to the _directory_ where the file resides. In any case, ACLs work as designed. Switching the component to kate... Fixed in kate-4.10.5-5.el7. There is a problem with deleting text. I'm able to edit and add lines/text, but when I try to delete it, It deletes partially or not at all. kate-4.10.5-5.el7 Reproducer: 1) # setfacl -m "u:test:rw" /etc/fstab 2) open the file in kate 3) add line and save 4) reopen 5) delete the line and save 6) reopen Ok, I managed to reproduce and also find a bug for this [1]. I'll try to backport this fix as well so this is complete. [1] - https://bugs.kde.org/show_bug.cgi?id=323693 I have the fix backported and verified locally, we just need the exception flag to be set so I can push it. Fixed in kate-4.10.5-6.el7.

Created attachment 1208068 [details] error message Description of problem: Users are unable to write to a file using 'kwrite', though they have ACL access. Version-Release number of selected component (if applicable): kwrite-4.10.5-3.el7.x86_64 How reproducible: Provide acl access to file for a user. Login to that user and try accessing the file. Steps to Reproduce: [1] # setfacl -m u:test:rwx /etc/fstab [2] Login by 'test' user [3] Open 'kwrite' and try writing /etc/fstab [4] Received a error saying "The document could not be saved as it was not possible to write to /etc/fstab. Check that you have write access to this file or that enough disk space is available". Actual results: kwrite doesn't allow the access provided for the user using ACLs Expected results: kwrite should allow the access provided for the user using ACLs Additional info: ACLs works fine for gedit
