Does it work without ACLs?

No, still the same, except I get one less userdb lookup in the log


   A1 SELECT Shared/user at sharer.dk
   A1 NO Mailbox doesn't exist: Shared/user at sharer.dk (0.006 + 0.000 + 
0.005 secs).

I've been trying a few things, still with no luck, but I noticed 
something that I find a bit strange.

On the wiki-page, https://wiki.dovecot.org/SharedMailboxes/Shared, the 
following is stated

"The location setting specifies how to access other users' mailboxes.
If
you use %%h, the user's home directory is asked from auth process via 
auth-userdb socket. See LDA for how to configure the socket. If the 
users' mailboxes can be found using a template, it's faster not to use 
the %%h."

But, looking at my location setting in my shared namespace

   location = 
maildir:/data/mail/%%d/%%n/maildir:INDEX=~/maildir/shared/%%u:INDEXPVT:~/maildir/shared/%%u

I am not using %%h, but rather a template.  It still seems to trigger a 
used-db lookup (and it did not do this in my old setup)

Could this be why it doesn't work? My user-lookup doesnt seem to return 
the full location (including /maildir), but only a home folder.
