+ ===== X2Go Session Broker Authentication Service =====
+ 
+ Package name: '''x2gobroker-authservice'''
+ 
+ On Debian based systems:
+ 
+ <code bash>
+ $ sudo apt-get install x2gobroker-authservice
+ </code>
+ 
+ The X2Go Session Broker Authentication Service normally gets installed on the machine that also has
''x2gobroker-daemon'' or ''x2gobroker-wsgi'' installed. The broker code itself runs as system user ''x2gobroker'' whereas the authentication service has to run as root. By security design, the functionality of the broker that requires root privileges has been separated from the rest of the broker.
+ 
+ The X2Go Session Broker Authentication Service requires root privileges for a few PAM based authentication backends. The default installation authenticates against PAM, on default Linux systems, PAM authentication (''pam_unix.so'') requires root privileges by the authentication process.
+ 
+ With other PAM setups (e.g. ''pam_ldap.so'') root privileges are not required and it is ok to not install ''x2gobroker-authservice''.
+ 
+ Furthermore, X2Go Session Broker can extended by other (non-PAM) authentication methods. The currently available authentication mechanisms in X2Go Session Broker are listed [[http://code.x2go.org/gitweb?p=x2gobroker.git;a=tree;f=x2gobroker/authmechs|here]].
