       <membership>
           <providers>
               <!--
                   This removes the default membership provider as defined
in the machine.config and
                   adds the same one but this time with more relaxed
password format and questions settings.
               -->
               <remove name="AspNetSqlMembershipProvider"/>
               <add name="AspNetSqlMembershipProvider"
