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_mailboxes/#user-shared-mailboxes-shared-mailbox-listing),
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.
