Ticket 497 - Console logins fail intermittenly
    
    Bug Description:  When there is a connection failure the admin server clears out
                      the "Users & Groups" data, and tries to rebuild it binding as
                      the SIE entry from o=netscaperoot.  This bind fails with an
                      error 53, and then we don't update the "Users & Groups" info.
    
    Fix Description:  If we geti an autentication failure, don't close the connection but
                      inext try to bind anonymously.  There must be aci's in place to allow
                      anonymous searches of the "cn=server group" entries.
