SSSD拒绝使用su登录LDAP：密码错误

10

我已经使用用户帐户设置了LDAP服务器。我已经成功配置了Rails应用程序以针对该LDAP服务器进行身份验证。我现在正在尝试将SSSD配置为针对LDAP进行身份验证，但它不喜欢单个用户密码。

错误：

$ su - leopetr4
Password:
su: incorrect password

SSSD可以识别用户，但不能识别密码：

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

用户记录如下所示：

# 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

这是上述base64解码后的用户密码哈希：

{SHA}oRNO1j31wmt5HVEafcm5f/SRfjo=

它与输出完全匹配 slappaswd -c {SHA} "that_password"

这是SSSD配置：

# cat /etc/sssd/sssd.conf

编辑：这/var/log/secure是登录尝试：

Nov 28 13:09:10 my_hostname su: pam_unix(su-l:auth): authentication failure; logname=root uid=1004 euid=0 tty=pts/1 ruser=leonsp rhost=  user=leopetr4
Nov 28 13:09:10 my_hostname su: pam_sss(su-l:auth): authentication failure; logname=root uid=1004 euid=0 tty=pts/1 ruser=leonsp rhost= user=leopetr4
Nov 28 13:09:10 my_hostname su: pam_sss(su-l:auth): received for user leopetr4: 7 (Authentication failure)

这是pam配置：

# cat /etc/pam.d/system-auth
#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required      pam_env.so

session     required      pam_unix.so
session     optional      pam_sss.so
session     optional      pam_ldap.so

PAM LDAP配置：

# cat /etc/pam_ldap.conf | grep -v '^#' | grep -v '^$'
base dc=my_domain,dc=com
uri ldaps://my_hostname.my_domain.com
ssl start_tls
tls_cacertdir /etc/openldap/cacerts
pam_password md5

也：

# authconfig --test | grep hashing
 password hashing algorithm is sha512

编辑2：通过pamtester进行身份验证有效，但通过su仍然不起作用：

[leonsp@my_hostname ~]$ pamtester login leopetr4 authenticate
Password:
pamtester: successfully authenticated

[leonsp@my_hostname ~]$ pamtester su leopetr4 authenticate
Password:
pamtester: Authentication failure

[leonsp@my_hostname ~]$ pamtester su-l leopetr4 authenticate
Password:
pamtester: successfully authenticated

  1. SSSD为什么不让我以该用户身份登录？

  2. 我需要做一些事情来配置SSSD以匹配基本{SHA}哈希吗？

  3. 如何login确定su/ 认证和/ 认证之间的区别su-l？

ldap  authentication  openldap  rhel6  sssd

根据sssd日志，sssd既对您进行了身份验证，又允许其访问。我会查看您的发行版中的/ var / log / secure文件或等效文件，以查看其中有哪些PAM消息以及是否还有其他PAM模块在起作用。btl使用tls_reqcert = never并不是一个好主意，因为这样一来，即使您的CA不信任的证书也将被允许。哦，最后su发出的错误密码消息可能有任何含义-这只是实用程序具有的默认错误消息。

@jhrozek我已经/var/log/secure为问题添加了pam配置详细信息
— Leo
您还可以编辑问题，以便日志也捕获身份验证失败吗？因为即使/ var / log / secure显示auth失败，但sssd_be日志仍显示成功：（Fri Nov 27 21:15:54 2015）[sssd [be [LDAP]]] [be_pam_handler_callback]（0x0100）：发送结果[ 0] [LDAP]能否请您编辑文件，以便捕获相同的PAM登录名，并且还有PAM响应程序日志？
— jhrozek 2015年
@jhrozek我已经重新捕获/var/log/secure并/var/log/sssd/*.log输出su - leopetr4。

嗯，这真的很奇怪，域日志中没有其他内容了吗？您可以增加debug_level（最高为10）吗？顺便说一句，我检查了sdap_save_user源，获取UUID的失败不是致命的。

抱歉，我不得不使用答案来问这些问题...

什么是的输出： authconfig --probe和 getent passwd leopetr4

您的系统身份验证与密码身份验证相同吗？您还能提供您的PAM登录文件吗？

您可能还想尝试在sssd.conf中设置cache_credentials = false，并在使用进行测试时清除缓存。 sss_cache -E

根据我的回答，错误消失了，并且没有立即明确的原因就开始起作用。authconfig --probe没有输出和getent passwd leopetr4输出leopetr4:*:9583:9583:Leo Petr 40:/mnt/home/leopetr4:/bin/bash

它是不令人满意的，但su - leopetr4并ssh leopetr4@my_hostname开始后，我设置的问题赏金工作不久。我花了一些时间思考为什么仍未得出明确的结论，因为它一开始就突然停止工作是很不好的。

我记得所做的一项更改是从和切换pam_password设置：/etc/pam_ldap.confmd5exop

#pam_password md5
pam_password exop

但是，从中断到工作的转变不是立即发生的，因此我犹豫将其归因于这种变化。
