Samba is ignoring "Valid Users"?

meetvora · 2019-06-10 11:35:05

I have set up a minimal arch server for my workplace that shares a data partition with other windows computers.

In my samba share config I have added a "Valid Users" line, which allows only two users to access the share, but the share connects successfully from any windows computer regardless of the credentials. What's going wrong here?

Here's the share config:

[share]
comment = staff
path = /data/share
valid users = ry staff
public = no
writeable = yes
printable = no

Add to your [share] "guest ok = No" and in your [global] add "map to guest = Bad User"

Also what's the output of "stat /data/share"?

Samba logs and journal logs would be nice in case there is something funky going on.

Added guest ok = no and map to guest = Bad User to my samba config. There was still no change or improvement. Whenever I connect using windows it just seems to gain access successfully how risky for a work computer.

Here's the output of stat /data/share

And finally, the samba logs
There's nothing significant in there.
A lot of errors: unable to open new log file '/usr/local/samba/var/log.%m': No such file or directory
and a few Request denies.
I could post them here in full if you think that would make it easier for you to help me out.

Pretty mysterious bug, nothing seems wrong...

Can you post the output of "sudo pdbedit -L -v"

Did you setup passwords for your users using "sudo smbpasswd -a myuser"

I would encourage to post the full samba log, just for completion

To rule out the d'oh moment, you did restart the smb services after changing the config, did you?
