title: How to setup RStudio Server authentication for CentOS 7
body: <p>I installed <a href="https://www.rstudio.com/products/rstudio-server-pro/" rel="nofollow noreferrer">RStudio Server (Open)</a> on a CentOS 6.3 server following the basic instructions, and was able to authenticate using my system user and password without any problems.</p>
  
  <p>However, when I tried the same (even same version of RStudio Server) on a CentOS 7.2 server, I'm unable to authenticate. It just tells me that the username and password aren't recognized. Any suggestions on how to fix this?</p>
