First of all i am i tell you about setup, i am using fedora-15

1. i have install 389 server, that is working fine.

my hostname is server1.example.com

dc=example,dc=com

2. i have configure dovecot.conf and conf.d/10-auth.conf configure properly but dovecot-ldap.conf having problem.

Below is my /etc/dovecot.conf

auth_verbose = yes
mail_debug = no

base_dir = /var/run/dovecot/
protocols = imap imaps pop3 pop3s
protocol lda {
  mail_plugins = quota
  postmaster_address = postmaster@example.com
  auth_socket_path = /var/run/dovecot/auth-master
  }
listen = *
shutdown_clients = yes
log_timestamp = "%b %d %H:%M:%S "
syslog_facility = mail
disable_plaintext_auth = no
login_chroot = yes
login_user = postfix
login_process_per_connection = yes
login_processes_count = 2
login_max_processes_count = 128
login_max_connections = 256
login_greeting = Welcome to Dovecot eMail Server.
login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c
login_log_format = %$: %s
#default_mail_env = maildir:/home/vmail/%d/%u
mail_location = maildir:/var/vmail/%d/%u
first_valid_uid = 108 # REMEBER THIS MUST BE CHANGED TO YOUR UID FOR "postfix" FROM /etc/passwd
mail_uid = 5000
mail_gid = 5000
pop3_uidl_format = %08Xu%08Xv
auth default {
    mechanisms = PLAIN LOGIN
    passdb ldap {
        args = /etc/dovecot/dovecot-ldap.conf
    }
    userdb ldap {
        args = /etc/dovecot/dovecot-ldap.conf
    }
socket listen {
                master {
                        path = /var/run/dovecot/auth-master
                                mode = 0600
                        user = vmail
                        group = vmail
                }
                client {
                        path = /var/spool/postfix/private/auth
                        mode = 0660
                        user = postfix
                        group = postfix
                }
        }
        user = vmail
}

/etc/dovecot/dovecot-ldap.conf

hosts = server1.example.com
auth_bind = yes
auth_bind_userdn = mail=%u,ou=People,dc=example,dc=com
ldap_version = 3
base = ou=People,dc=example,dc=com
dn = cn="Directory Manager,dc=example,dc=com"
dnpass = mypassword
#deref = never
scope = subtree
user_attrs = quota=quota=maildir:storage
user_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u))
pass_attrs = mail,userPassword
pass_filter = (&(objectClass=VirtualMailAccount)(accountActive=TRUE)(mail=%u))
default_pass_scheme = MD5

When i use configuration and checking pop for chris@example.com which have password 123. But it is not working, it is giving me error.
