DigiKam and ACL

Thats how I use digikam here. It works well.

Yes, that definitely ensures that any files created in that directory will
be given the same group as that directory. Digikam works well with this.

[You may already have done this, but this configuration also needs you to
have created a group containing both you and your wife. For this example
lets call this group "family". Then change the group of the shared
directory: "chgrp family sharedfolder". Or add -R if you already have some
files in that directory which need their group changed over: "chgrp -R
family sharedfolder". Any *new* files created in that directory will now be
given the group "family"]

>> and group permissions:  

No..... Digikam (and almost everything else) uses umask to determine the
permissions of the files it creates. (k)ubuntu currently sets the umask to
002 for shell logins (via /etc/profile), but uses 022 for graphical
processes started via kdm/gdm. Im not sure why; this has always seems
somewhat counterproductive.

I recommend adding "session optional pam_umask.so umask=002"
to /etc/pam.d/common-session. This sets the umask to 002 for all logins.

I hope this helps,
