Hi List,

While facing the astonishing amount of replies, yet I found some time to 
dig on this issue, and it appeared the problem came from the lack of the 
option

   wide links = yes

on the concerned share.

Activating this option forced me to globally disable

   unix extensions = no

as I understood from this note :

http://www.samba.org/samba/news/symlink_attack.html

What I'm keeping to see as weird is that using the IP address still 
allows me to use wide links abilities AND unix extensions...

Anyway, this one is solved, let's face the next one.
