根据网上的经验,说是与64位库路径,修改/etc/pam.d/login 中最后一行,

[root@gpsdb ~]# more /etc/pam.d/login
#%PAM-1.0
auth [user_unknown=ignore success=ok ignore=ignore default=bad] pam_securetty.so
auth       include      system-auth
account    required     pam_nologin.so
account    include      system-auth
password   include      system-auth
# pam_selinux.so close should be the first session rule
session    required     pam_selinux.so close
session    include      system-auth
session    required     pam_loginuid.so
session    optional     pam_console.so

# pam_selinux.so open should only be followed by sessions to be executed in the user context
session required pam_selinux.so open
session optional pam_keyinit.so force revoke
session required /lib/security/pam_limits.so

修改 /lib/security/pam_limits.so 为 /lib64/security/pam_limits.so即可.

修改后,本地用户即可登陆.
