PERMISSION ISSUE

SUSE Linux Enterprise Server SLES Configure-Administer
1

Hello. I’ve set up a SAMBA share but I can only write to it when I set all the permissions to 777. I’ve tried 775 and 755 but I still have the same issue. I can’t even write to the directories when I log in as root.

Hi,

when you’re able to write to a share (via its 777 permissions) on the client, as which user id does the file appear when looking at it via a local “ls -n” / “ls -l” (on the SaMBa server)?

This may well be a “user mapping” issue… it’s not about the user names, but about user ids. I guess that when you’re trying to write via the (mounted) share, the client user gets mapped to some other ID than whom the directory belongs to. And it’s independent from the invoking user - the effective user is associated with the mounting session, unlike with NFS. So if you mount the share using the Samba user “someone”, every write will act on behalf of “someone”, no matter which user is issuing the write operation on the client.

(Or I have misunderstood the issue.)

Regards,
J
