This has been a debated issues on the technical list. There's a new parameter in 3.0.21pre1 called 'map read only'. Let me summarize it like this. In the absence of 'store dos attributes = yes' and the ability to represent DOS attribute bits separately from permission bits, we have two choices. (a) May the read only DOS attrib bit to the inverse of the user write bit (this is what we did prior to the 3.0.20 series), or (b) represent the read only attribute based on whether the user can actually write to the file. If the 'R' DOS attribute is set, Windows will not allow you to delete the file IIRC which is probably what you are hitting. In 3.0.21pre1 'map read only = yes' should give you 3.0.14a behavior. The problem in the current 3.0.20 behavior (which might be considered a bug) is that we do not take the parent directory permissions into account when determining whether the user has write access or not to a given file. And hence this is another argument to stay away from user space access checks. But we have no choice with the changes in WinXP sp2 and file deletion. Does this help explain the behavior? cheers, jerry ===================================================================== Alleviating the pain of Windows(tm) ------- http://www.samba.org GnuPG Key ----- http://www.plainjoe.org/gpg_public.asc "There's an anonymous coward in all of us." --anonymous -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFDV6kVIR7qMdg1EfYRAlfkAJ9lTSgNasw6zs9QhxfNWCe4s8vuYgCfZBTc d3C1mpsyuyqN23QBSfEavs4= =rUnL -----END PGP SIGNATURE----- -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba
