Description J. J. Franzen 2006-03-02 21:04:11 UTC
I'm seeing rather odd behavior on a XServe running OS X Server 10.4.5.  Files created with permissions of 777 are changed to 077 when modified by a user other then the original owner.  Also, ownership changes from the original creator of the file to the person who just modified it.  I have to assume this is not the usual behavior, right?  Any help here would be greatly appreciated.  Thanks,

This is almost certainly a result of application file saving behaviour. Many applications will rewrite the file when saving rather that just updating it. This is a safety technique designed to minimise the chances of data loss if an error occurs while saving.

If you want to verify this, please attach a trace of the behaviour. See http://wiki.samba.org/index.php/Capture_Packets for how to capture a trace.

Closing, sine this is almost certainly expected application behaviour.
