ASP.NET

I am in my Web.config file and I am doing authentication mode. I have an error saying that, "The 'forms' attribute is not allowed. Why am I getting this error? How can i fix this safely? I also have over 5,000 users in a database. Is there a way for me to authenticate those users with out typing them all in the web.config file?

<system.web>
        <compilation debug="true" targetFramework="4.0" />
      
      <authentication mode="Forms">
        <forms forms="401kApp" loginUrl="/Login.aspx" />
      </authentication>
      
    </system.web>

Here is what I have changed:

<system.web>
        <compilation debug="true" targetFramework="4.0" />
      
      <authentication mode="Forms">
        <forms loginUrl="/Login.aspx" />
      </authentication>
      <membership defaultProvider="SqlProvider"
      userIsOnlineTimeWindow="15">
        <providers>
          <add
            name="SqlProvider"
            type="System.Web.Security.SqlMembershipProvider"
            connectionStringName="SqlServices"
            applicationName="SACSCOCLogin1.1"
            enablePasswordRetrieval="true"
            enablePasswordReset="true"
            requiresQuestionAndAnswer="false"
            requiresUniqueEmail="true"
            passwordFormat="Hashed"
            maxInvalidPasswordAttempts="5"
            passwordAttemptWindow="10" />
        </providers>
      </membership>
    </system.web>

</configuration>
