My complete conf is attached at the original mail.

It's install_prefix. The log says:
IMAP(user) [10363]: Error: userdb lookup: 
connect(/usr/local/dovecot-1.2.rc5unpatched/var/run/dovecot/auth-master) 
failed: Permission denied

But the conf has:

base_dir: /var/run/dovecot/

Also, auth default | socket | master contains the setting:
path: /var/run/dovecot/auth-master

Deliver works with this conf without the symlink.

Hmm, I'll investigate where the group "mail" comes from.

Well,

a) as there is no way to return/use the mail_location of the sharing user, 
the location is possibly wrong anyway, because mail_location is not 
neccessarily derived from the user's home in the same way always.

b) I considered mail_location stable after setup. But you are right, that 
this is not neccessaily so. One would need some sort of book keeping to 
keep the redundant data in shared-mailboxes.db in sync.
