[Samba] Confusion berween file and direcory

[Felix]

I have some trouble with a samba 3.5.8 server when setting directory 
attributes. On a windows XP I execute a small peace of code that calls 
'SetFileAttributes' for the directory 'test-dir' located on the samba 
server. Using log level 10 I find this:

As I said, 'test-dir' is a directory. If my understand of the log is 
correct samba confuses a directory with a file? Why would this happen?
