Hello,
I am trying to switch from LDA to LMTP on a Postfix/Dovecot setup, but something is going wrong.
I have followed the directions at: https://wiki.dovecot.org/HowTo/PostfixDovecotLMTP
Here is a session from dovecot.log:
Aug 4 12:19:42 vmail2 dovecot: lmtp(3152): Connect from local Aug 4 12:19:42 vmail2 dovecot: auth: ldap(imaptester@noa.gr): unknown user Aug 4 12:19:42 vmail2 dovecot: lmtp(3152): Disconnect from local: Successful quit Aug 4 12:19:42 vmail2 dovecot: lmtp(3152): Connect from local Aug 4 12:19:42 vmail2 dovecot: auth: ldap(nmilas@noa.gr): unknown user Aug 4 12:19:42 vmail2 dovecot: lmtp(3152): Disconnect from local: Successful quit Aug 4 12:19:42 vmail2 dovecot: imap(nmilas): save: box=Sent, uid=31, msgid=c84ae059-854d-12bc-6aa2-9099cc2977b2@noa.gr, size=445, vsize=459, from=Nikolaos Milas nmilas@noa.gr, subject=Test (12) - vmail2, flags=(\Seen)
What is going wrong?
It seems authentication is not working correctly with this setup. If understand right, dovecot is querying ldap with the whole mail address and not with the local part only (which is the username), as I would expect.
FILE: /etc/dovecot/dovecot-usrdb-ldap.conf
hosts = localhost tls = no base = ou=people, dc=noa, dc=gr scope = onelevel ldap_version = 3 dn = uid=auth,ou=Sys,dc=noa,dc=gr dnpass = secret auth_bind = yes user_filter = (uid=%u) pass_filter = (uid=%u) pass_attrs = uid=user,userPassword=password auth_bind_userdn = uid=%u,ou=people,dc=noa,dc=gr user_attrs = roomNumber=quota_rule=*:bytes=%$,uid=home=/home/vmail/%u iterate_filter = (objectClass=*)
You are searching for the complete username (%u = user@domain) but it sounds like you only want the localpart (%n). See:
