SSSD su ile LDAP oturumunu reddediyor: yanlış şifre

10

Kullanıcı hesaplarıyla bir LDAP sunucusu kurdum. Bu LDAP sunucusunda kimlik doğrulaması yapmak için Rails uygulamasını başarıyla yapılandırdım. Şimdi SSSD'yi LDAP'ye karşı kimlik doğrulaması için yapılandırmaya çalışıyorum, ancak bireysel kullanıcı şifrelerini sevmiyor.

Hata:

$ su - leopetr4
Password:
su: incorrect password

SSSD kullanıcıyı tanır, ancak şifreyi tanımaz:

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

Kullanıcı kaydı şöyle görünür:

# 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

Base64 kod çözme işleminden sonra yukarıdaki kullanıcı şifresi karması şöyledir:

{SHA}oRNO1j31wmt5HVEafcm5f/SRfjo=

İle tam olarak eşleşir slappaswd -c {SHA} "that_password"

İşte SSSD yapılandırması:

Ayrıca:

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

Edit 2 : Pamtester ile kimlik doğrulaması çalışıyor, ancak su ile çalışmaya devam ediyor:

[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 neden bu kullanıcı olarak giriş yapmama izin vermiyor?

  2. SSSD'yi temel {SHA}karmaları eşleştirecek şekilde yapılandırmak için yapmam gereken bir şey var mı ?

Sssd günlüklerine göre, sssd hem kimliğinizi doğruladı hem de erişime izin verdi. Hangi var PAM iletileri ve belki de başka bir PAM modülü hareket varsa görmek için dağıtım / var / log / secure dosya veya eşdeğer bakmak. btw kullanarak tls_reqcert = asla iyi bir fikir değildir, çünkü CA'nız tarafından güvenilmeyen sertifikalara bile izin verilir. Oh ve nihayet su tarafından yanlış şifre mesajı bir şey ifade edebilir - bu sadece yardımcı programın sahip olduğu varsayılan hata mesajı.

@jhrozek ben ekledim /var/log/securesorusuna ayrıntıları ve PAM yapılandırma

Soruyu, günlüklerin kimlik doğrulama hatasını da ele geçirmesi için düzenleyebilir misiniz? / Var / log / secure kimlik doğrulaması hatası gösterse de, sssd_be günlükleri başarı gösterir: (Cum Kasım 21 21151554 2015) [sssd [be [LDAP]]]] [be_pam_handler_callback] (0x0100): Gönderilen sonuç [ 0] [LDAP] Dosyaları, aynı PAM girişinin yakalanıp PAM yanıtlayıcı günlükleri orada olacak şekilde düzenleyebilir misiniz?

@jhrozek Yeniden yakaladım /var/log/secureve /var/log/sssd/*.logçıktısını aldım su - leopetr4.

Hmm, bu gerçekten garip, etki alanı günlüğünde başka bir şey yok mu? Debug_level'i artırabilir misiniz (10 en yüksek)? btw sdap_save_user kaynağını kontrol ettim ve UUID alma hatası ölümcül değil.

Bu soruları sormak için cevap kullanmak zorunda olduğum için üzgünüm ...

Çıktısı nedir: authconfig --probeve getent passwd leopetr4

Sistem doğrulamanız, şifre doğrulamanızla aynı mı? PAM giriş dosyanızı da sağlayabilir misiniz?

Ayrıca sssd.conf dosyasında cache_credentials = false ayarını denemek ve aşağıdakileri kullanarak test ederken önbelleği temizlemek isteyebilirsiniz sss_cache -E

Cevabım başına hata ortadan kalktı ve hemen açık bir neden olmadan çalışmaya başladı. authconfig --probeçıktı ve getent passwd leopetr4çıktı yokleopetr4:*:9583:9583:Leo Petr 40:/mnt/home/leopetr4:/bin/bash

Bu yetersiz, ama oluyor su - leopetr4ve ssh leopetr4@my_hostnameben soru üzerine ödül set hemen sonra çalışmaya başladı. Bunun net bir sonuca varmadan neden olduğunu düşünmek için biraz zaman harcadım, çünkü başlangıçta aniden çalışmayı bırakması kötü olurdu.

Ben yapım hatırlıyorum değişikliklerden biri anahtarlama olduğunu pam_passwordayarı /etc/pam_ldap.confgelen md5ve exop:

#pam_password md5
pam_password exop

Ancak, kırıktan çalışmaya geçiş hemen gerçekleşmedi, bu yüzden bu değişime atfetmekten çekinmeyin.
