Samba share not writable

[net-flyer]

Hi everybody,
I'm banging my head against samba once more..

Samba 3.5.6 on a Centos 6.0 Linux server.

I have a samba share that I can access but I can't write to.
The Linux directory is writeable and the Samba configuration for the share is "read only = no" but the smbstatus output says RDONLY nonetheless.
This happens both from a Win7 and from an XP machine.

Outputs below.... and many thanks to anyone will help!

Share permissions:
drwxrwxrwx. 14 sigwix sigwix 4096 27 dic 19:06 /u/share

smbstatus output:
Samba version 3.5.6-86.el6_1.4

For all who may be concerned

Problem was caused by SELinux policy (SELinux installed by default on Centos6).
