[ILUG] CentOS 4 NIS client weirdness

[Niall O Broin]

I have a CentOS 4 (=~ RHES4) box which is a NIS client of a SuSE 9.3  
box, which is behaving very oddly. It is connected to the master -  
ypwhich shows the master's name, ypwhich -m shows the maps, and ypcat  
of a map shows what it should.

However, strange things happen on trying to login as a NIS user. I  
can't login on the console - it's as if the password is wrong. I can  
ssh in, but when I do that, /etc/bashrc isn't sourced. It certainly  
feels somehow PAM related, but I'm not sure how. I have run    
authconfig --enablenis --enablemd5  and  /etc/pam.d/system-auth  
reflects that - I have

password    sufficient    /lib/security/$ISA/pam_unix.so nullok  
use_authtok md5 shadow nis


These lines from the log

Aug 24 19:21:48 pumori login(pam_unix)[2733]: authentication failure;  
logname=LOGIN uid=0 euid=0 tty=tty1 ruser= rhost=  user=niall
Aug 24 19:21:51 pumori login[2733]: FAILED LOGIN 1 FROM (null) FOR  
niall, Authentication failure

Aug 24 19:44:04 pumori sshd(pam_unix)[5897]: session opened for user  
niall by (uid=0)


show a failed login on the console, and then a successful (to some  
extent) login by ssh.


Any bright ideas?
