sssd密码更改弹出窗口

Question

我已经将我们的一个跳转服务器从openldap/nscd迁移到sssd客户端。服务器运行的是Ubuntu 14.04 x64。一切正常，除了一个非常重要的功能:密码重置对话框不弹出时，用户验证与过期的密码。我们在ldap服务器(OpenLdap 2.4)上设置了90天保留期的策略。在/etc/sssd/sssd.conf上使用不同的标志并没有带来预期的结果，这里是sssd.conf

# LDAP sssd config
[sssd]
debug_level = 8
domains = mydomain.local
config_file_version = 2
reconnection_retries = 3
services = nss, pam, ssh, sudo

[domain/mydomain.local]
debug_level = 8
cache_credentials = true
entry_cache_timeout = 600
ldap_search_base = dc=mydomain,dc=local
ldap_sudo_search_base = ou=SUDOers,dc=mydomain,dc=local
id_provider = ldap
auth_provider = ldap
chpass_provider = ldap
sudo_provider = ldap
subdomain_homedir = /home/%d/%u
ldap_uri = ldaps://10.10.10.10
ldap_tls_reqcert = allow
account_cache_expiration = 7
ldap_schema = rfc2307
ldap_pwd_policy = shadow
ldap_chpass_update_last_change = true

reconnection_retries = 3

filter_users = backup,bin,daemon,Debian-exim,games,gnats,irc,list,lp,mail,man,messagebus,news,root,smmsp,smmta,sshd,sync,sys,syslog,uucp,uuidd
reconnection_retries = 3
enum_cache_timeout = 300
entry_cache_nowait_percentage = 75

[pam]
debug_level = 8
pam_verbosity = 8
reconnection_retries = 3
offline_credentials_expiration = 7
offline_failed_login_attempts = 5
offline_failed_login_delay = 15

[sudo]
debug_level = 8

我对这里的任何方向都很高兴

作为临时解决方案，我在登录脚本中使用以下函数，该函数从/etc/bash.bashrc调用

calculate_pwd_age() {
 local MAX_AGE=90
 let "shdw_epoch = $(ldapsearch -x -LLL -H ldaps://10.0.0.1 "uid=${USER}" shadowLastChange | awk 'NR==2{print $2}')"
 let "today = $(date +'%s') / 86400"
 let "shdw_diff = ${today} - ${shdw_epoch}"
 if [[ ${shdw_diff} -ge ${MAX_AGE} ]]; then
   echo -e  "\nYour password has expired. Please change it right now:\n"
   sleep 2
   passwd
 fi
}
