utf-8 characters cause permission denied error

[StuartYeates]

Binary package hint: samba

Accessing a remote windows server using the standard gnome GUI connection tool works for the share as a whole. Accessing a file including a macron in the name (a directory called "Māori") gives a permission denied error ("You do not have the permissions necessary to view the contents of "Māori".").

The share doesn't normally require a username and password to access. Everything works fine from windows.

I asked aobut this on irc and was told to report it as a bug.

cheers

Could you please attach your smb.conf file

[Thierry Carrez (ttx)]

Could you check if you manage to access the file with smbclient ? That will allow us to tell if the problem is in samba or gnome.

[StuartYeates (stuart-yeates)]

smbclient fails.

There is also an interesting feature where the columns of the directory listing are out by one for this column. This leads me to suspect that the problem may be in unicode normalisation. There are two ways of representing ā in Unicode, a single character and an 'a' followed by a compose character. Every sane person uses the single character, but alas one of the standards in use in my organisation (MARC) uses the compose character.

One other detail that may be relevant:

I've attached the /etc/smb.conf file.

gah .. that should have been "I've attached the /etc/samba/smb.conf

Also my language settings ..

[Chuck Short (zulcss)]

Can you try mounting the directory with iocharset=utf8?

Thanks

Can you run smbclient with -d 9 please and attach the output.

Thanks
chuck

[StuartYeates (stuart-yeates)]

As requested, here's a log attempting to connect with -d 9 set

[Jeremy Allison (jra-samba)]

Actually, what we need is a debug level 10 from smbclient (9 isn't good enough) and a wireshark trace of the smbclient connection to the Windows server.

Attach them to the samba bug:

https://bugzilla.samba.org/show_bug.cgi?id=7241

Jeremy.
