Ticket 47850 - "nsslapd-allow-anonymous-access: rootdse" makes login as "admin" fail at the first time
    
    Bug Description:  If anonymous bind access is restricted, console logins using
                      just the RDN fails.  This is becuase the console does anonymous
                      searches to find the real user.
    
    Fix Description:  Added new config parameters to adm.conf to specfiy a bind DN and
                      password that is only used to search for users.
    
                      This "authentication" user should reside in o=netscaperoot, and have
                      access permissions to search the "config" database and the "users"
                      database.
