You are successfully logging in as those other users, but the login process is launching the users’ login shell, and when /bin/bash is executed, the login session returns:
 “/bin/bash: Permission denied”.  Then the login session exits and you log out

My first guess is that either /bin/bash’s permissions are broken, and root either uses a different shell or the permissions only allows root. 

The output of “rpm -V bash” should tell you what is wrong with the package.


Now, personally, I see a long out of date system with ssh access and broken bash, and I immediately think “compromised system”. So I’d suggest caution.
