1, edit /etc/pam.d/system-auth

 

[root@xabuild1 ~]# head -n 4  /etc/pam.d/system-auth  | grep -v ^#
auth        required      /lib/security/$ISA/pam_listfile.so item=user sense=allow file=/etc/allowusers onerr=succeed
[root@xabuild1 ~]#

 

2, add one line to /etc/pam.d/ssh(rsh)

[root@xabuild1 ~]# head -n 5  /etc/pam.d/sshd  | grep -v ^#
auth       include      system-auth
[root@xabuild1 ~]#

 

3, Added accounts in /etc/allowusers:

[root@xabuild1 ~]# cat /etc/allowusers
cnbuild
tfan
liwang
llhu
