Linux: password is not properly logged in, log prompt could not get shadow information for user

Today, when playing Centos7 again, try to modify the port under SSH. Because SELinux is turned on by default, the SSHD service does not start properly if you do not modify the file configuration to modify the port.

However, when I modify the port 22 will still not be able to log in normally. This time to check the login log prompt as above: (because before the successful landing, fortunately there is no window closed)

Finally found is/etc/ssh/sshd_config below the Usepam no this option of the "pot" ~ inexplicably this has become no

After you modify it to Yes. Restart Service Normal Login
