postfix ldap sasl 验证问题 ！！！！

sunfeng116

用testsaslauthd测试验证通过，但是通过smtp登录postfix就不行了

配置文件:
/etc/sysconfig/saslauthd

SOCKETDIR=/var/run/saslauthd
MECH=ldap
FLAGS=

/usr/lib/sasl2/smtpd.conf

pwcheck_method: saslauthd
mech_list:login plain

/etc/postfix/main.cf

smtpd_sasl_auth_enable = yes
smtpd_sasl_path = smtpd
smtpd_sasl_local_domain = $myhostname
smtpd_sasl_security_options = noanonymous
smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated, reject_unauth_destination
broken_sasl_auth_clients = yes

错误：postfix/smtpd[25821]: warning: localhost.localdomain[127.0.0.1]: SASL login authentication failed: authentication failure
