+                If true, then the face browser will show all users on the
+                local machine.  If false, the face browser will only show
+                users who have recently logged in.
+              </para>
+              <para>
+               To provide more detail on how this option works. When this key
+               is true, GDM will call fgetpwent() to get a list of local users
+               on the system.  The Face Browser also will display any users
+               that have previously logged in on the system (for example
+               NIS/LDAP users).  It gets this list via calling the ck-history
+               ConsoleKit interface.  It will also filter out any users which
+               do not have a valid shell (valid shells are any shell that
+               getusershell() returns.  <filename>/sbin/nologin</filename> or
+               <filename>/bin/false</filename> are considered invalid shells
+               even if getusershell() returns them).
+              </para>
+
+              <para>
+               If false, then GDM more simply only displays users that have 
+               previously logged in on the system (local or NIS/LDAP users) by
+               calling the ck-history ConsoleKit interface.
+              </para>
+
+              <para>
+               In both cases, GDM filters out any users with a UID less than
+               500 (or 100 if running on Solaris).  Such users are considered
+               system users.
