[Samba] Samba on RHEL 6: Permission denied when mounting FUSE partition

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 (my own implementation of) 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.

On both machines I have disabled firewall and I set SELinux to permissive.

 

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:

 

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/        // (FUSE
share)

 

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/     // (FUSE
share)

 

The share has the necessary permissions for root to connect:

drwxr-xr-x. 5 root root  4096 Dec 10 15:15 iFSG-EE

 

I am getting the ls event multiple times under RHEL 6, but 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,

bjorn

 

 

- 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
