Hello all , I am running a redhat 7.2 machine with the regular pam rpms that came with the d istribution . The rpms are : ---------------- 1) pam_krb5-1.46-1 2) pam_smb-1.1.6-2 3) pam-0.75-14 4) pam-devel-0.75-14 I am having a problem using nis authentication with this pam rpms , every time i try to login i am getting a message in /var/log/messages : sshd(pam_unix)[4575]: authentication failure; logname= uid=0 euid=0 tty=ssh ru ser= rhost=kuku.domain.com user=kuku1 I have to say that it doesnt metter what authentication method i use , i can use telnet or ssh or any other application , i get the same response . Both default authentication schems are enabled on my system from redhat installa tion setup : shadow & md5 . My nis server is running shadow password authentication , but in the system it s elf the md5 & shadow are both enabled . The ypserv version is : ----------------------- ypserv-1.3.9-3 My pam.d/system-auth : ------------------------- auth required /lib/security/pam_env.so auth sufficient /lib/security/pam_unix.so like_auth nullok auth required /lib/security/pam_deny.so account required /lib/security/pam_unix.so session required /lib/security/pam_limits.so session required /lib/security/pam_unix.so password required /lib/security/pam_cracklib.so retry=3 type= password sufficient /lib/security/pam_unix.so nullok use_authok md5 shadow nis pasword required /lib/security/pam_deny.so I must say that when i changed the pam_unix.so to pam_pwdb.so in each of the pam_unix.so entries everything started to work . I guess it is because pam_pwdb use by defau lt the shadow password authentication scheme . So I don't understand why redhat6.2 for example use pam_unix.so module and every thing works fine and under redhat7.2 it doesn't work ,,, when i actually install ed the machine from scratch and using the regular pam module configured by the r edhat installation setup to use both md5 & shadow & nis . All my other machines are perffectly working except the 7.2 distribution . I would really like an answer to this problem because i did my best to solve the problem but i still don't understand why it doesn't work . Thanks . P.S: --- the nis client is bounded on the machine and i have a /home dir so this is not the problem . Best Regards Nissim Penias .
