Fwd: Samba client delete's root-only files

Just to clarify two points in my previous cry for help (see mail below)...


The file I used for testing had read AND write permissions for root, and no 
permissions for anyone else.  And yet it could be deleted by any Windows 
user (through SAMBA).

If I chmod the file to having ONLY read access by root (no write access) 
then Windows users cannot delete the file.

It appears as though SAMBA is doing reads as the windows user, but is doing 
deletes as root?


So far the only SAMBA servers I've found that do not have this problem have 
"read only = yes".  So it appears to be a problem with all our writable 

Any ideas, anyone?
