[Dovecot] Problem with LDAP query

[Aleix Dorca]

Hi people,

first message to this list.

I've a problem with dovecot 1.0.15 (debian latest package) and an LDAP query. The situation is the following. My LDAP users have multiple mail addresses (field 'mail') and mail should be able to be sent to any of these and the mail should always end on the user's mailbox. This is not working for me now.

My dovecot-ldap.conf relevant config shows:

user-attrs = uid=user
user_filter = (&(objectClass=posixAccount)(|(uid=%n)(mail=%u)))

This correctly detects multiple addresses but mail always end in folder (from dovecot.conf):

mail_location = maildir:/home/vmail/%n/Maildir

So if user at domain gets a mail it ends in /home/vmail/user/Maildir but if the same user gets an email to user-alt at domain it ends in /home/vmail/user-alt/Maildir instead of /home/vmail/user/Maildir.

I've been debugging and I get this on my mail.log file:

Jun 10 12:41:29 horologium deliver(user-alt at domain): auth input: user-alt at domain
Jun 10 12:41:29 horologium deliver(user-alt at domain): auth input: user=user
Jun 10 12:41:29 horologium deliver(user-alt at domain): auth input: uid=5000
Jun 10 12:41:29 horologium deliver(user-alt at domain): auth input: gid=5000
Jun 10 12:41:29 horologium deliver(user-alt at domain): maildir: data=/home/vmail/user-alt/Maildir
Jun 10 12:41:29 horologium deliver(user-alt at domain): maildir: root=/home/vmail/user-alt/Maildir, index=/home/vmail/user-alt/Maildir, control=, inbox=

Since I'm in version 1.0.15 can't use the mailLocation with the $ substitution.

Anyway, any help will be appreciated.
