Comment 46 for bug 206439

I don't know if it helps, but for me it hapens only for one of my shares (except home which is invisible). I have security=user and few shares. All are accesible except one which is set to read/write (as the only of them).
There are parts of my smb.conf (I think the most important):
[global]
security = user
encrypt passwords = true
update encrypted = no
unix password sync = no
nt acl support = no
domain logons = yes
domain master = yes
local master = yes
preferred master = yes
wins support = no
announce as = NT server
[pub]
writable = yes
locking = no
path = /home/samba/pub
public = yes
[mmedia]
writable = no
locking = no
path = /home/samba/mmedia
public = no
writelist = @domadmin

There's no problem to access mmedia share, but Hardy couldn't mount pub share in any way.
