[Samba] samba 4 alpha 5 with user_xattr error: system cannot find the file specified

[Ying Hu]

Hi,
    I am trying samba4 alpha5 because I would like to use the feature of
xattr for ACL. I followed the howto.txt comes with it exactly. I found that
if I use user_xattr in /etc/fstab, I got "System cannot find the file
specified" error very often (more than 50% of the time) when I try to create
a file from a windows machine using share test (dir /data/test on samba
server). If I don't user user_xattr, everything is fine. I can provide more
logs if asked. Please help me.
thanks,
Ying
