Samba: Permission denied only when mounting fuse partition

iternity · 06-08-2011, 07:56 AM

Hello,

I am successfully connecting my Windows box to a RHEL 5 over SMB. This works for both mounting a regular share as well as a fuse mountpoint.
On RHEL 6 I can only mount a regular share, but not a fuse mountpoint. I am getting a Permission Denied error.

Does anybody know why this could be happening?

I have attached below:
- my smb.conf file (it is the same on both machines)
- my smbuser file (it is the same on both machines)
- output from smbclient command for RHEL 6
- some debug output from my fuse implementation for RHEL 5
- some debug output from my fuse implementation for RHEL 6

Also, ls -ldZ gives the following outputs (iFSG-EE is the name of the fuse mountpoint)

RHEL 5, regular share:
drwxr-xr-x root root root: object_r:mnt_t regshare/

RHEL 5, fuse share:
drwxr-xr-x root root system_u: object_r:fusefs_t iFSG-EE/

RHEL6 regular share:
drwxr_xr_x. root root unconfined_u: object_r:mnt_t:s0 regshare/

RHEL6 fuse share:
drwxr_xr_x. root root system_u: object_r:fusefs_t:s0 iFSG-EE/

The share has the necessary permissions for root to connect (I have also tried to set it to 777, but it was the same problem):
drwxr-xr-x. 5 root root 4096 Dec 10 15:15 iFSG-EE

I am getting the ls event under RHEL 6 in my fuse debug output, but I am not sure where that Permission denied comes from?
Any pointers would be greatly appreciated,

Oh, and also the Samba versions are different:
RHEL5: Version 3.0.33-3.29.el5_6.2
RHEL6: Version 3.5.6-86.el6

Could a newer version of Samba cause the problem?

thanks!

- smb.conf:

[global]
workgroup = WORKGROUP
netbios name = localhost.localdomain
server string = Samba Server Version %v
security = user
browseable = yes

[fuseshare]
path = /mnt/iFSG-EE
browseable = yes
writeable = yes
read only = no
guest ok = yes
valid users = root

[regshare]
path = /mnt/regshare
browseable = yes
writeable = yes
read only = no
guest ok = yes
valid users = root

- smbusers:

root = administrator admin root
smbroot = smbroot
nobody = guest pcguest smbguest

- output from smbclient command to RHEL 6

[root@localhost iFuseNative]# smbclient -L 192.168.9.58
