I want to use Dovecot LDA (or rather LMTP) use as local deliver with
Postfix MTA. Users are in LDAP DB with structure as:
dn: cn=username, ou=rank, o=myorg
cn: username
objectClass: Person
gidNumber: uNNN
uidNumber: gNNN
userPassword: (somehow hashed, can only bind verification)
homeDirectory: /Home/$rank/$username
mailActive: 0/1
mail: usera@OneDomain
mail: userb@SecDomain (not all users have 2+ addresses]
uid: username
groupMembership: group DN (can be multiple times for different groups)
...
where:
- cn = uid = expected IMAP login username (which hasn't @domain part)
- user1 (and user2) isn't always same as username
?? What means this requirement?
Now I not know, how to solve IMO diferent requirements to userdb:
- LDA/LMTP need LDAP userdb unit, that can retrieve the name from an
email address (ie for "usera@myDomain" returns cn/uid (as dovecot
"username").
For LDA, just use another config.
- IMAP server need LDAP userdb unit, that will have the user login
(username) as the input parameter, and which returns information
whether or not the user exists.
user_filter = (&(|(mail=%n)(uid=%u))(mailActive=1)(objectClass=person))
this assumes that usera (without @domain) is not the username of another
entry and that there is one entry for each mail address only. Users may
login with their mail address.
On the other hand, can you solve the aliases in LDAP into usernames by
Postfix:
http://www.postfix.org/ldap_table.5.html
user_attrs = \
=home=%{ldap:homeDirectory}, \
=uid=%{ldap:uidNumber},
=gid=%{ldap:gidNumber},
=quota_rule=*:bytes=%{ldap:quotaBytes},
=namespace/default/separator=%{ldap:mailSeparator}
Can anyone explain how these constructions work?
And what do mean attribute notations in the form '=attr=' or '@attr='
or 'quota_rule=*:storage=100M' ?
Nowhere have I found a sufficiently comprehensible description of these
constructions...
