Userdb problem
Hello
I am trying to move authentication from ldap to passwdfile.
Autentication works, but clients do not find the mails.
With ldap I have :
root@email:~ # doveadm auth login erwan x
passdb: erwan auth succeeded
extra fields:
user=erwan
userdb extra fields:
erwan
home=/var/db/mailboxes/erwan
/var/db/mailboxes/erwan=/var/db/mailboxes/erwan
uid=587
gid=587
auth_mech=PLAIN
With passwdfile I get
root@email:~ # doveadm auth login erwan x
passdb: erwan auth succeeded
extra fields:
user=erwan
userdb extra fields:
erwan
home=/var/db/mailboxes/erwan,uid=587,gid=587
uid=587
gid=587
auth_mech=PLAIN
The only difference is this
"/var/db/mailboxes/erwan=/var/db/mailboxes/erwan" (which is the place
where email is stored).
What is the problem with this ?
auth configuration is :
passdb {
driver = passwd-file
args = scheme=SHA512-CRYPT username_format=%n
/usr/local/etc/dovecot/users
}
userdb {
driver = passwd-file
args = username_format=%n /usr/local/etc/dovecot/users
# Default fields that can be overridden by passwd-file
#default_fields = quota_rule=*:storage=1G
default_fields = home=/var/db/mailboxes/%n,uid=587,gid=587
# Override fields from passwd-file
#override_fields = home=/home/virtual/%u
override_fields = home=/var/db/mailboxes/%n,uid=587,gid=587
}

dovecot-2.3.17: "Panic: file ioloop.c: line 865"
Hello,
since the upgrade from dovecot-2.3.16 to 2.3.17 I get 'Panic'-errors in
the system-log of my replicator hosts. See below for log messages,
doveconf-output and gdb-backtrace. Storage filesystem is ZFS.
The error seems to be correlated with exactly one user-mailbox, this
user is repeatedly noted as 'failed' in replication status, although
replication of this mailbox seems to work, as the mailbox status shows
always the identical size on both replicators. The error can be produced
by forcing replication of this individual mailbox.
Is there anything I can do to repair this mailbox?
Thanks for any hints,
Andreas

2.3.17: Panic on LMTP deliveries
Hello Since the doevcot update to 2.3.17 i get a panic if a mail is delivered with lmtp. In the logs i get these messages: lmtp(r...@example.com)<21067>: Error: lmtp-server: conn 10.0.0.105:52981 [1]: rcpt r...@example.com: duplicate db: User r...@example.com doesn't have home dir set, disabling duplicate database lmtp(r...@example.com)<21067>: Panic: file imem.c: line 65 (i_strconcat): assertion failed: (str1 != NULL) lmtp(r...@example.com)<21067>: Fatal: master: service(lmtp): child 21067 killed with signal 6 (core dumped) In the running config userdb does not return the field “home” and therefor a user does not have a “mail_home” only a “mail_location”. If i change the config to provide a “mail_home” it works, but due to the directory structure i can not change this yet.
