X64 Linux cannot be resolved from local character interface login

There are often strange things happening. In other words, I have a server in charge of squid, remote landing good has been her good. Today to change the gateway, so I took a monitor on-premises operation.

When you have finished typing the username root password * Enter Yo, let me lose again?? Well, I lost again, or this! Dead and Alive on account authentication interface landing not on.

Ah, the server has been hacked?? Log in with a laptop but everything is fine. To view the server security log:

Tail-50/var/log/secure

The following error was found:

May 2 18:45:41 Server1 Login:pam Unable to Dlopen (/lib/security/pam_limits.so) May 2 18:45:41 Server1 Login:pam [ERROR: /lib/security/pam_limits.so:wrong ELF Class:elfclass32] May 2 18:45:41 Server1 login:pam adding faulty module:/lib/sec Urity/pam_limits.so May 2 18:45:45 Server1 Login:pam_unix (Login:auth): Authentication failure; Logname=login uid=0 euid=0 tty=tty1 ruser= rhost= user=root May 2 18:45:46 Server1 login:failed LOGIN 1 from (null) for R Oot, authentication failure 2 18:46:05 Server1 login:failed login 2 from (null) to root, authentication failure may 2 18:46:15 Server1 Login:pam_unix (login:session): Session opened for user root by login (uid=0) May 2 18:46:15 Server1 log In:module is unknown

Since the operating system is RedHat As5.3 X64 Prior experience implies that this is likely to be related to the storage path of the X64 class file. Then edit the login configuration file:

Vim/etc/pam.d/login

Take the next line of the session required/lib/security/pam_limits.so

Modified to: Session required/lib64/security/pam_limits.so

Save and exit. Try to log in locally and succeed! The log didn't get any more errors.
