found 432971 2:3.2.5-4
thanks

Coming back on this old bug report by Martin....


With the following smb.conf:

[global]
   guest account = nobody
   workgroup = MAISON
   server string = Le portable de Kiki (samba %v)
   map to guest = Bad User

[homes]
   comment = Home Directories
   browseable = yes
   read only = no
   create mode = 0700

[public]
directory mask=0700
browseable=yes
comment=Public
read only=no
create mask=0770
public=yes
path=/var/tmp/samba-test

I can mount:

root at mykerinos:/var/log/samba> mount -t cifs -o guest //localhost/public /mnt --verbose
parsing options: rw,guest

mount.cifs kernel mount options unc=//localhost\public,ip=127.0.0.1,user=root,ver=1,rw,guest
root at mykerinos:/var/log/samba>

*Without* "map to guest = Bad User", I can't:

root at mykerinos:/var/log/samba> mount -t cifs -o guest //localhost/public /mnt --verbose
parsing options: rw,guest

mount.cifs kernel mount options unc=//localhost\public,ip=127.0.0.1,user=root,ver=1,rw,guest
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

And the log shows:

So, I *confirm* that this bug still exists in 3.2.5. "-o guest" does
*not* connect anonymously to the mounted share.
