Hello,
I am setting up a new server and migrating my Dovecot 1.2.9 config to
the new 2.2.9 version. There wasn't much to keep from the old version so
I had to recreate the config from scratch. Now I think I'm done but I
can't login to IMAP. The log says this:
dovecot: auth: Error:
prefetch(box@****.de,2001:****:7765,<bzAOP5QJXwAgAQpgEAXJAZyOMB1qBXdl>):
userdb lookup not possible with only userdb prefetch
dovecot: auth: Error:
userdb(box@****.de,2001:****:7765,<bzAOP5QJXwAgAQpgEAXJAZyOMB1qBXdl>):
user not found from userdb prefetch
dovecot: imap: Error: Authenticated user not found from userdb, auth
lookup id=178651137 (client-pid=13711 client-id=1)
dovecot: imap-login: Internal login failure (pid=13711 id=1) (internal
failure, 1 successful auths): user=<box@****.de>, method=PLAIN,
rip=2001:****:7765, lip=2a01:****:2, mpid=13717, TLS,
session=<bzAOP5QJXwAgAQpgEAXJAZyOMB1qBXdl>
That doesn't help me a lot. Here's parts of my configuration, dumped
with 'dovecot -n':
# 2.2.9: /etc/dovecot/dovecot.conf
# OS: Linux 3.13.0-40-generic x86_64 Ubuntu 14.04.1 LTS
auth_mechanisms = plain login
disable_plaintext_auth = no
namespace inbox {
inbox = yes
location =
mailbox Drafts {
special_use = \Drafts
}
mailbox Junk {
special_use = \Junk
}
mailbox Sent {
special_use = \Sent
}
mailbox "Sent Messages" {
special_use = \Sent
}
mailbox Trash {
special_use = \Trash
}
prefix =
}
passdb {
args = /etc/dovecot/dovecot-sql.conf.ext
driver = sql
}
plugin {
quota = maildir
}
protocols = imap pop3
userdb {
driver = prefetch
}
protocol imap {
mail_max_userip_connections = 100
mail_plugins = quota imap_quota
}
What's the problem here? How can I resolve this issue?
You did fulfill the requzirements for prefetch to work documented in the
wiki?
