[K12OSN] smbldap adjusting permissions from Windows

This is not resolved if we don't know why permissions changes weren't working on folders.

When viewing the properties pages of a share, from a Windows XP SMB client, if you switch to the "Security" tab, you are looking the permissions for the NTFS folder that is shared.  You are not looking at the share ACL, but the folder ACL.  To see share ACL from XP, try pointing Computer Management at your Samba server.  According to my look, my home-folder-share has an ACL of Everyone:FullControl.  That's not likely to cause any problem.  But every entity on every folder ACL has "special" permissions.  This problem needs exploration.

I have a feeling that the solution is somewhere in unix-side facls.  Like, if the filesystem is loaded "with ACL support", which I forget how to do, the changes to permissions might work correctly.

I'm really just trying to provide an open share that anybody can create
a file/folder in, while enabling users to change permissions on the
files/folders that they create.  It seems to be working now, but it
seemed odd to me that I couldn't use the first permissions screen to do
it (well, it worked for files, but not folders).

Thanks for your help.
