[SOLVED]Sharing files between user accounts.

I want two user accounts to have full access to a common set of files. I have created a group for that purpose but even with umask settings I always seem to end up with a situation where one user does not have full permissions to one of the "shared" files (e.g. because an application uses it's own internal umask).

Essentially, I want both accounts to act as a single account for certain files, and I have considered sharing the UID, but that creates problems with user names and also exposes all files owned by either user to the other. I have also considered solutions using bindfs, but managing the mount points might become complicated, so I'm hoping that there's a simpler solution.

So, my question is what is the best way to ensure that two users always have full access to a set of files in a given location, which still enabling both users to have private files elsewhere?

Set the group sticky bit (chmod g+s) on the shared directory and make sure its ownered to the shared group. Files created in that directory will be ownered to the group owner of the directory.

Thanks, falconindy.

The setgid bit does most of what I need. The rest can be done with access control lists, which I discovered as I was reading up on setgid:
