Hi, we have such configuration in our Dovecot; it is configured with virtual users and acl. To enable access of userA mailbox to userB, first I have to add userB to userA acl, and then I put userA username in an ARBITRARY_FIELD of userB record in our ldap (if you use a db for your account, the configuration could be more simple). We use the ARBITRARY_FIELD to limit the access of other users mailboxes: the field is not writable by the user, only by administrators.
Our config files:
/etc/dovecot/conf.d/auth-master.conf.ext ... passdb { driver = ldap master = yes
args = /etc/dovecot/dovecot-ldap.conf.masterusers pass = yes default_fields = userdb_mail=maildir:/path_to_mailboxes/%1{login_user}/%{login_user}:INDEXPVT=/path_to_indexes/%1n/%n/shared/%{login_user} }
and in /etc/dovecot/dovecot-ldap.conf.masterusers ... pass_attrs = uid=user,userPassword=password pass_filter = (&(uid=%n)(accountStatus=active)(ARBITRARY_FIELD=%{login_user}))
to login, you have to use the same way of a masteruser:
Login: userA*userB Password: userB_password
Cheers, Marco

do you maybe mean shared mailboxes: http://wiki.dovecot.org/SharedMailboxes
I don't want shared mailboxes. I have to access the other mailboxas a complete separate account from my personal one.
I think I can achive this with master user, but I need to found away to configure permissions so the real user has access to all folders in the other mailbox.
