即使登录有效，pam_unix sshd 身份验证也会失败？

我有一台配置了 winbind 和 samba 以提供 Active Directory 身份验证的服务器。Active Directory 集成工作正常，但是每当我进行身份验证时，都会看到以下错误：

错误

验证：

May 11 00:25:29 SERVER sshd[28119]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=x.x.x.x  user=USERNAME

须藤：

May 11 01:33:14 SERVER sudo: pam_unix(sudo:auth): authentication failure; logname=USER_NAME uid=2005125 euid=0 tty=/dev/pts/2 ruser=USER_NAME rhost=  user=USER_NAME

配置

/etc/samba/smb.conf：

[global]
        workgroup = WORKGROUP
        realm = DOMAIN NAME
        security = ADS
        winbind enum users = Yes
        winbind enum groups = Yes
        winbind use default domain = No
        winbind separator = +
        kerberos method = secrets and keytab
        idmap config * : backend = autorid
        idmap config * : range = 1000000-19999999
        idmap config * : rangesize = 1000000
        template shell = /bin/bash
        netbios name = SERVERNAME
