+      <listitem><para>Keeping track of users and sessions, their processes and their idle state. This is implemented by
+      allocating a systemd slice unit for each user below <filename>user.slice</filename>, and a scope unit below it
+      for each concurrent session of a user. Also, a per-user service manager is started as system service instance of

+
+      <listitem><para>Generating and managing session IDs. If auditing is available and an audit session ID is already set for
