It would be super awesome if ShinyProxy could support user authentication and authorization using native authentication mechanisms on Linux, just like the Shiny Server Pro version.
These days it's very easy to configure Linux systems to use remote identify services like FreeIPA, LDAP or Active Directory using the SSSD and/or Samba packages.
ShinyProxy could benefit from this because it would be very easy for ShinyProxy administrators to configure and it would provide a great alternative to the more advanced ShinyProxy authentication backends but be just as powerful
