Hi Patrick,

If I knew how to do it / had time, why would I ask if someone is
interested in this?

No, it isn't. It's SMTP's job when a mail comes in to do the LDAP lookup
to find the mailbox ID to deliver the mail to. That's just working fine
and is not what I am asking for.
What I am talking about is the IMAP *user* that want's to login to her
mailbox. For the sake of this discussion, using a service like
http://www.mail2web.com/. The MUA to *read* mail in the *mailbox* is
talking to the IMAP daemon. No SMTP involved there.

Subject: Sponsoring a canon_user plugin for LDAP lookup
Hi!
We are in needed of a canon_user plugin.
The scope is quite simple:
We use technical IDs for mailbox names in Cyrus IMAPd. Our mailboxes
are called mb00001, mb00002, mb00003, ... You get the concept. In our
MTA we have defined aliases for the actual email addresses that point
to a mailbox, so each user can have multiple email addresses connected
to a single mailbox, for example:
info@xxxxxxxxxx -> mb000002
john.doe@xxxxxxxxx -> mb000002
john.doe@xxxxxxxxxx -> mb000002
someome@xxxxxxxx -> mb000816
This is handles by the MTA (Exim) querying LDAP for object like this one:
dn: mailAlias=someone,ou=...
dc: else.com
mailAlias: someone
objectClass: mailAlias
objectClass: mailDomain
objectClass: top
mailAliasedName: mb000816
We've also configured Cyrus IMAPd to query LDAP via the SASL layer
where we store user objects, such as:
dn: uid=mb000816,ou=.....
uid: mb000816
objectClass: account
objectClass: simpleSecurityObject
objectClass: top
userPassword: xxxxxxx
Now users would like to be able to use one of their email addresses to
login, rather than having to remember their mbXXXXXX id.
I understand that this is what a canon_user plugin would be suitable
for, so it would just take the user's input of a username (in this
case someone@xxxxxxxx), do a lookup for a mailAlias object in LDAP
which has dc={domain part of email address} and mailAlias={local part
of email address} and return the mailAliasedName attribute, which id
the Cyrus IMAPd mailbox id.
From looking at a sample I would guess that this will be 100 lines of
code or less. But we don't have any experienced C programmer and as
this is meant for production use, I would appreciate this done by
someone who knows that he doing. And it would be great if this had a
chance to become part of the codebase.
So as nobody obviously felt the need for that before, we're thinking
of paying someone to do it and donate the code. As I think this is a
quite limited scope, we'd be hoping this could be done for a lower
3-digit USD figure?
Anyone intersted?
Regards,
Torsten
