Hi everybody,

I am trying to construct a LDAP dict for shared mailboxes.

There is a lot of documentation available but nothing specific to this usecase. I could not find anything useful on Google nor in the mailinglist archives :-(

The best start point seems to be the doc on shared mailbox dictionaries (https://doc.dovecot.org/configuration_manual/shared_mailboxes/shared_mailbox...), in particular the example for SQL dict. But obviously LDAP is different than SQL. The dictionaries page (https://doc.dovecot.org/configuration_manual/dict/) has  LDAP example but it looks like it does not contain all the bit and pieces I need.

Following the structure of the SQL example, I come to something like this:

map { pattern = shared/shared-boxes/user/$to/$from base_dn = ou=shared mailboxes,dc=example,dc=com filter = (&(objectClass=group)(mail=%{from})

  fields { from_user=$from to_user=$to } }

The "to_user" / "$to" should be filled with the 'uid' or 'email' of a nested group lookup of the 'member' fields of the group.

What are the mechanics to get that done? Does anyone has an example or pointer to documentation or is a LDAP dict for shared-mailboxes not possible / supported? And in the latter case, suggestions about possible alternatives are welcome :-)

FYI. the LDAP implementation I am using is a recent Samba4 ad-dc.
