如何在 CentOS 上使用 Dovecot + IMAP + PAM 进行身份验证？

  • 772

我按照此处的建议设置了 Dovecot IMAP 以使用 PAM：

http://wiki2.dovecot.org/PasswordDatabase/PAM

PAM/鸽舍

[root@ip-172-31-15-65 pam.d]# cat dovecot
#%PAM-1.0
auth    required        pam_unix.so nullok
account required        pam_unix.so

/etc/dovecot/conf.d/auth-system.conf.ext

passdb {
  driver = pam
  args = failure_show_msg=yes

userdb {
  driver = passwd

当我尝试按照此处的建议进行测试和调试时http://www.courier-mta.org/authlib/README.authdebug.html

[root@ip-172-31-15-65 pam.d]# telnet localhost 143
Trying 127.0.0.1...

但是我可以通过 SSH 登录

[root@ip-172-31-15-65 conf.d]# ssh starrychloe@localhost
starrychloe@localhost's password:
Last login: Sun Apr  6 04:18:05 2014 from xxxxxxx.cable.mindspring.com
[starrychloe@ip-172-31-15-65 ~]$

我确实重新启动了 Dovecot。

我已经改过密码了。

    它与此有关，但我不明白为什么。

    service auth-worker {
  user = $default_internal_user
}
service auth {
  unix_listener /var/spool/postfix/private/auth {
    mode = 0660
    user = postfix
  }
}
