last_login LDAP - killed with signal 11 (core dumped)
Hi
I am trying to configure the last_login plugin with LDAP dictionary
which is causing dict service to crash. Not sure if this is a bug or
some configuration parameter I'm getting wrong?
Running latest dovecot but was having the same problem in earlier
version 2.2.25
# dovecot --version
2.2.28 (bed8434)
I have configured dovecot like so:
dovecot.conf (before conf.d/*.conf:
dict {
#quota = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext
#expire = sqlite:/etc/dovecot/dovecot-dict-sql.conf.ext
lastlogin = ldap:/etc/dovecot/dovecot-ldap-dict.conf.ext
}
conf.d/10-master.conf
service dict {
# If dict proxy is used, mail processes should have access to its
socket.
# For example: mode=0660, group=vmail and global
mail_access_groups=vmail
unix_listener dict {
mode = 0660
user = vmail
group = vmail
}
}
conf.d/20-imap.conf:
protocol imap {
# Space separated list of plugins to load (default is global
mail_plugins).
mail_plugins = $mail_plugins last_login
# Maximum number of IMAP connections allowed for a user from each IP
address.
# NOTE: The username is compared case-sensitively.
#mail_max_userip_connections = 10
}
90-plugins.conf
plugin {
#setting_name = value
#last_login_dict = proxy::lastlogin
last_login_dict = proxy:dict:lastlogin
zlib_save = gz
zlib_save_level = 6
}
dovecot-ldap-dict.conf.ext:
uri = ldap://ldap.internal
bind_dn = cn=Manager,dc=mail,dc=com
password =
tls = no
debug = 1
map {
pattern = last-login/$user
filter = (&(mail=%{user})(objectClass=mailUser)) # the () is required
base_dn = o=domains,dc=mail,dc=com
username_attribute = mail
value_attribute = lastLoginTime
fields {
mail=$user
}
}
I don't see dovecot ever making a connection to the LDAP server I've
configured in the dovecot-ldap-dict.conf.ext file.
Log shows
