SSSD使用su拒绝LDAP登录：密码错误

我已经设置了一个包含用户帐户的LDAP服务器.我已成功配置Rails应用程序以对此LDAP服务器进行身份验证.我现在正在尝试配置SSSD以对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=com
uid: leopetr4
cn: Leo Petr 40
sn: 40

# search result

# numResponses: 2
# numEntries: 1

这是base64解码后的用户密码哈希：

{SHA}oRNO1j31wmt5HVEafcm5f/SRfjo=

它与slappaswd -c {SHA}“that_password”的输出完全匹配

这是SSSD配置：

# cat /etc/sssd/sssd.conf

reconnection_retries = 3
sbus_timeout = 30
services = nss,pam

[pam]

当我尝试使用su – leopetr4时,这是SSSD日志：

编辑：这是登录尝试的/ var / log / secure：

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): received for user leopetr4: 7 (Authentication failure)

这是pam配置：

# cat /etc/pam.d/system-auth

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进行身份验证工作,但它继续无法通过su工作：

[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
