[Samba] samba mkdir fail

[xiaodong hu]

dear samba team:
I porting samba source code to Android 4.4,and  mount PC's share folders to
mount point successfully.

Problem is  i can not mkdir or create new file,under share folder
directory,show no permmission.even though i use adb  shell command  and get
root permission to mkdir under share folder directory,it also shows
permission denied.But i can delete files and rename file or folder under
share folder.

I use the same binary files of samba on Android 4.3,it works well.

so ,do you know where the problem is? thanks.
