[Samba] Strange homes share

[Alain B]

Hi,
There is something strange about homes share through samba (any version).

Beside the username any user can see another username, different for 
each of us but which is in fact the same share and not the one of the 
other username !?!

If in the share options, I choose browseable = YES, I get a new share 
'homes' beside myself and the other 'ghost' username which is, again, my 
share.

Any idea??

Alain.
