We are using CIFS to mount user's home directories in our desktops. Unix Extensions are needed in order to start Gnome/KDE sessions over a CIFS fs. Desktop systems are running AlmaLinux 8.6 (4.18.0-372.19.1.el8_6 --- CIFS Version 2.29 ---) and home dirs are mounted with these options: sec=krb5,domain=XXXX,vers=1.0,noforceuid,noforcegid,nobrl,iocharset=utf8 The server is running AlmaLinux 8.6 (4.15.5-8.el8_6), with userquota enabled and as domain member. The desktop users cannot modify the permissions of a directory inside their home when the directory has not 'rwx' permissions for the owner. However, this does not happen with samba 4.13.3. [user@desktop ~]$ mkdir FOLDER [user@desktop ~]$ ls -ld FOLDER drwx------ 2 user users 0 sep 15 09:35 FOLDER [user@desktop ~]$ chmod u-rwx FOLDER/ [user@desktop ~]$ ls -ld FOLDER ls: cannot access 'FOLDER': Permission denied [user@desktop ~]$ chmod u+rwx FOLDER/ chmod: cannot access 'FOLDER/': Permission denied
I'm afraid without more debugging the cause of the problem from your side this bug report will not end up anywhere. Increase the log level and make a network trace and find out where things are going wrong and come up with more details here. Eventually support from a company like those listed at https://www.samba.org/samba/support/globalsupport.html might be a good option also.
(In reply to Björn Jacke from comment #1) As Bjorn says, we are going to need more information, amongst which would be your smb.conf files. I did notice this: drwx------ 2 user users 0 sep 15 09:35 FOLDER Why is the group 'users' and not 'Domain Users' if this is a Unix domain member ?
