Thanks Aki for the answer.
I did some tests and found a solution. I write down my experience It
could be useful to someone.
First I putted "passwd-file" passdb (only) before "pam" passdb, as Aki
suggested,
but "illegal seek error" persisted.
Then I putted both "passwd-file" passdb and "static" userdb before "pam"
passdb and "passwd" userdb (used for local user),
but that generated a strange behavior because "static" driver overrides
info also for local user.
Finally I putted both "passwd-file" passdb and "passwd-file" userdb
before "pam" and "passwd"
and that works without errors.
My working dovecot config:
host-prompt# dovecot -n
# 2.1.7: /etc/dovecot/dovecot.conf
# OS: Linux 3.2.0-5-686-pae i686 Debian 7.11
auth_mechanisms = plain login
auth_username_format = %Ln
listen = *
log_timestamp = "%Y-%m-%d %H:%M:%S "
login_greeting = Server ready.
mail_full_filesystem_access = yes
mail_location = mbox:~/:INBOX=/var/mail/%u:INDEX=/var/index/%u
mail_privileged_group = mail
passdb {
args = scheme=MD5-CRYPT username_format=%n /etc/dovecot/users
driver = passwd-file
}
passdb {
driver = pam
}
protocols = " imap"
service auth {
unix_listener /var/spool/postfix/private/auth {
group = postfix
mode = 0660
user = postfix
}
user = root
}
service imap-login {
inet_listener imap {
port = 0
}
}
ssl_cert = to avoid writing uid,gid,home for each user, but in the end, with
passwd-file and
override_fields i got the desired scenario.

Claudio

Hi,
I recently configured dovecot to manage auth
for both local and virtual user.
When i login as a virtual user (claudio.panetta) I get the following
message:
dovecot: auth: Error:
passwd(claudio.panetta,160.97.62.1,): getpwnam()
failed: Illegal seek
but login is ok and sending/receiving email is ok,
how can, if possible, I suppress this error message?

Hi! Put the file based passdb before the pam one. Also not sure what you are
trying to do with the static userdb. It looks like you wanted to use
passwd-file?
