samba issues

[broken_symlink]

hi! i have been having problems with samba and checking out repos using svn. When svn tries to checkout a repo it will give me an error about not being able to move the .svn dirs under the top level of what it is trying to checkout. It will say permission denied when it tries to move them. I am also not able to remove the source dirs. when i build things. I can extract the source for something as user a on a samba share and then build stuff, but when i try to delete the source as user a i get an error that says permission denied. Here is my smb.conf

after adding exec to my fstab i seem to be able to checkout svn repos from the client now. but i still am not able to build things and then delete the source. i also added create mask = 0777, directory mask = 0777, force create mode = 0777, and force directory mode = 0777 to my smb.conf, but they do not seem to be having any affect. When i do ls -al it still shows -rwxr-xr-x. Any ideas?
