Unable to allow SSH access for new user

I currently have an issue, what I am trying to do is disable the root login and use ssh to login as a new user, then su to root when needed.

I am unable to actually allow the user to login through root. I am able to login through SSH on root, but not the user I have made.

I have used the AllowUser command, still no luck.

Anything there is to fix this?

I am using CentOS 07.

$ grep <newuser> /etc/passwd
<newuser>:x:1000:1000::/home/<newuser>:/bin/bash]
