[Samba] Please help me how to fix "read only" file problem

[Jaroslav Fojtik]

Dears,

I have tested SVN on samba drive and it totally fails.
Please help me to navigate in source code, where attributes are set.
It would be better either to fix it or at least to block R attribute 
to set.

fojtik at dvouramenna:~/ESC_sro/Kancl/.svn$ chmod 777 entries
fojtik at dvouramenna:~/ESC_sro/Kancl/.svn$ ls -la entries
-rwxrwxrwx  1 fojtik users 300 Mar  7 13:38 entries

M:\ESC_sro\Kancl\.svn>attrib entries
A          M:\ESC_sro\Kancl\.svn\entries

M:\ESC_sro\Kancl\.svn>attrib +r entries
M:\ESC_sro\Kancl\.svn>attrib entries
A    R     M:\ESC_sro\Kancl\.svn\entries

fojtik at dvouramenna:~/ESC_sro/Kancl/.svn$ ls -la entries
-r-xr-xr-x  1 fojtik users 300 Mar  7 13:38 entries

M:\ESC_sro\Kancl\.svn>attrib -r entries
Access denied - M:\ESC_sro\Kancl\.svn\entries

>From this point there is no way to handle a file on samba drive.
Access is denied. But user "fojtik" still could change right on 
Linux site. There is something wrong.

thank you
