[Samba] Samba 4 DC log.smd flooded with Conversion error

[Kinglok, Fong]

Dear all,

After setting dos charset = CP950 (which is the codepage for traditional chinese), the same error still remains.

Furthermore, I have tried testing in a real production environment by the following steps:

1.  In smb.conf,
     I create a share called Chinese and increase the log level to 10.
	[global]
		workgroup = YAUOICHURCH
		realm = SAMBA4.YAUOI.ORG
		netbios name = FILE
		server role = active directory domain controller
		dns forwarder = 192.168.107.1
		log level = 10
		unix charset = UTF8
		dos charset = CP950
	[netlogon]
		path = /usr/local/samba/var/locks/sysvol/samba4.yauoi.org/scripts
		read only = No
	[sysvol]
		path = /usr/local/samba/var/locks/sysvol
		read only = No
...
	[Chinese]
		path = /home/chinese
		read only = No

2.  In the file server, I have created a directory /home/chinese and also, inside it, I have open a folder called "中文測試" and I have tested the name is in UTF-8.

3.  I made use of Windows 7 64-bit Traditional Chinese as client to try to browse the share Chinese and then the folder (the client has joined the domain already) and I install wireshark to capture the packet.
The wireshark capture is here:

4.  the log.smbd still show

Should I file a bug for it?
