[SOLVED] Windows APPCRASH when opening security tab on Samba share

mfoley · 12-16-2023, 11:26 AM

I don't know if this is a Windows or Linux question, but I'll start here as LQ people usually have the answers.

I have a new Samba file server. In Windows (10) Explorer, I can open the share with \\dc1.hprs.locl, and I see my folders. One folder is named 'Users' I can put files into that folder, no problem. However if I right-click on 'Users > Properties > Security, Explorer crashes. This does not happen on the other two folder (sysvol and netlogin). I find nothing in the Linux log files. The Windows event log gives

Permissions on the share are:

Code:

# ls -l -R /redirectedFolders/
/redirectedFolders/:
total 4
drwxrwxr-x 2 root root 4096 2023-12-16 11:47 Users/

/redirectedFolders/Users:
total 8
-rwxrwxr-x+ 1 3000000 users 17 2023-12-16 11:47 testing.txt*

Note that the testing.txt file is one I created from the Windows computer, so it would appear at least write permissions exist.

Any idea what's up with this?

I got this fixed! Since sysvol and netlogin folders didn't crash when I selected their Properties > Security, I reasoned there must be something about permissions or ownership afoot. Sure enough:

Code:

# ls -ld /var/lib/samba/sysvol/

drwxrwx---+ 3 root 3000000 4096 2023-11-29 21:16 /var/lib/samba/sysvol/

Both of those directories, created by provisioning, are members of group 3000000 which I presume is some administrative group.

Cloning sysvol to Users solved the problem!

Code:

drwxrwx---+ 2 root 3000000 4096 2023-12-17 00:13 Users/
