SSSD 拒绝 LDAP 登录 su: 不正确的密码

Question

我已经使用用户帐户设置了 LDAP 服务器。我已经成功地配置了一个 Rails 应用程序来验证这个 LDAP 服务器。我现在正在尝试将 SSSD 配置为针对 LDAP 进行身份验证，但它不喜欢个人用户密码。

错误：

$ su - leopetr4
Password:
su: incorrect password

SSSD 识别用户，但不识别密码：

$ id leopetr4
uid=9583(leopetr4) gid=9583(leopetr4) groups=9583(leopetr4)

这是用户记录的样子：

# ldapsearch -x -W -D "cn=admin,dc=my_domain,dc=com"  -H ldaps://my_hostname.my_domain.com "(uid=leopetr4)"
Enter LDAP Password:
# extended LDIF
#
# LDAPv3
# base <dc=my_domain,dc=com> (default) with scope subtree
# filter: (uid=leopetr4)
# requesting: ALL
#

# leopetr4, People, my_domain.com
dn: uid=leopetr4,ou=People,dc=my_domain,dc=com
uid: leopetr4

# search result

result: 0 Success

# numResponses: 2
# numEntries: 1

以下是对上述内容进行 base64 解码后的用户密码哈希：

{SHA}oRNO1j31wmt5HVEafcm5f/SRfjo=

它完全匹配的输出 slappaswd -c {SHA} "that_password"

这是 SSSD 配置：

# cat /etc/sssd/sssd.conf
[sssd]

reconnection_retries = 3
sbus_timeout = 30

这并不令人满意，但是在我对这个问题设置赏金后不久就开始工作了su - leopetr4。ssh leopetr4@my_hostname我花了一些时间思考为什么会这样，但没有得出明确的结论，因为它突然停止工作对它来说是不好的。

我记得所做的一项更改是将pam_password设置/etc/pam_ldap.conf从md5和切换到exop：

#pam_password md5
pam_password exop

然而，从损坏到工作的变化并不是立即发生的，所以我犹豫是否将其归因于这种变化。
