[Pkg-samba-maint] Bug#412574: it generates directories with the name of the share

[Santiago Garcia Mantinan]

Package: samba
Version: 3.0.24-2
Severity: normal

If there is a share whose name is the same as the name of a directory on
that share (it seems that this is not case sensitive), when you access the
directory weird things happen, like finding directories that don't exist.

I have tested this with latest 2.6 kernel cifs up to 2.6.20.1 running etch
with the samba servers running etch and sid, this doesn't happen if the
server is a sarge based samba, and it only happens with cifs, not with
smbfs, so maybe it is not something wrong with samba but with the cifs
filesystem driver, with the old samba on sarge it doesn't happen, so I
don't know if it is samba's or cifs client's fault.

I think the best way to explain the weird behaviour here is by an example:

I create a share on the samba server like this:

[deb]
   comment = buggy stuff
   writable = no
   locking = no
   path = /bug
   public = yes
   browseable = no

Inside the share I create a directory called deb, it could also be called
DEB and things would also work weird, even though I believe behaviour is a
little bit different. Inside the deb directory I create a file named other,
that's it. No other files or directories exist inside the share's directory.

Don't know what else to add, if more info is needed just tell me and I'll
try to gather it.
