Non-alphanumeric character in web.config. How to win?

Question

ASP.NET

I use provider membership. There is such a thing as non-alphanumeric characters in a password. I want to disable them. I set minRequiredNonalphanumericCharacters="0" in web.config , but it doesn't help, membership still doesn't accept a password without such a character. How to remove this option?
Content of web.config :

<membership defaultProvider="AspNetSqlMembershipProvider" userIsOnlineTimeWindow="20">
      <providers>
        <clear />
        <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider"
        connectionStringName="LocalSqlServer"
        enablePasswordRetrieval="false"
        enablePasswordReset="true"
        requiresUniqueEmail="true"    
        requiresQuestionAndAnswer="false"
        minRequiredNonalphanumericCharacters="0"
        applicationName="/" />
      </providers>
    </membership>

Answer 1

Try this
<providers> <clear /> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" /> </providers>
. Will it work?
