Samba: error 13 : permission denied

[on5sl]

Hello,

I've got a freebsd server which runs samba. This samba share has file permissions and samba permissions "activated". Everything works well on the system administrator account, but not on the other user accounts...
When i do mount /home/bram/nas with the user bram everything is fine:

bram@katia-desktop:~$ mount /home/bram/nas/
bram@katia-desktop:~$ df -h

Here is a comparization of the two users:

bram@katia-desktop:~$ cat /etc/fstab

As you can see, everything is the same? I've also tried to activate some more user right in users/groups but that doesn't help...
I did search after another solution and found that the nounix option could help..but still the same error
I really don't get the issue...maybe it is a bug? I

edit:
and yes, I've read this thread off course...maybe it's more relevant to post my question there?
I can also read in the cifs page that when using the option user it tries to apply the user on currently logged in...the user option in my fstab is for my ubuntu so that every user can mount it...and the credentials are used to specify the samba user. Maybe there is going something wrong there?
