We have a Mac 10.5.8 server with an AFP file share that is accessed by employees in the "staff" group membership. This is a production environment and client files get added to this directory automatically through the use of the application called Switch by Callas.
We have propagated permissions so anything in the AFP file share inherits these permissions:
macadmin (server admin account) : Read and Write
staff: Read and Write
Everyone: Read and Write
The problem is with .zip files. When a zip file is uploaded, only the person who unzips the file has permissions. The zip file itself has the correct permissions, but the extracted contents have these permissions:
drewk(random user who unzipped the files): Read and Write
staff: read only
everyone: read only
These files need to have read and write access for everyone, not just the person who decompressed the file.
We have done some UMask edits, but those seem to go back to the default settings after a server reboot.
Not sure if it helps, but we use Open Directory in conjunction with Active Directory. These users log into the Mac and PC with the same credentials , but only use the PC's for the timecard software.
Any help would be greatly appreciated. I can provide more info if needed.
