I installed RSTUDIO for cents per the instructions. when I launch the browser, connect to port 8787 and attempt to login I keep getting authentication failure. This is NOT RSTUDIO PRO therefore I don't have a license key. I was told STUDIO authenticates using the PAM config file.
Here is my screen shot
[root#node09] /usr/lib/rstudio-server/bin/pamtester --verbose studio tym16 authenticate
pamtester: invoking pam_start(studio, tym16...)
pamtester: performing operation - authenticate
pamtester: Authentication failure.
