Probably the easyest way is to set the SUID and SGID bits on the
directories in question.  That way, and new files created will have the
same owner and group.  What is probably happening is that when A makes
changes to a file, a new file is being created with the changes
information, and then the old one is renamed as a backup, or deleted,
depending on the software being used to edit the file.  (The file being
updated this way, instead of rewriting the origional file is not
controled by Samba.)  The problem is that the new file is owned by user
A, instead of being owned by the person that owned the origional file.

If the folders are seperate shares, you can control who the files are 
owned by as part of the share definition.  Check out the "force user", 
"force group", and "create mode" options.


    Do not meddle in the affairs of dragons,
 for you are crunchy and taste good with ketchup.
