Umbraco V7.7.2

Hello Dan, Thanks for your effort to provide a package for us to use. Here's some question hope you can help. Thanks a lot.

After install the package

web.config :

<membership defaultProvider="MyMembersMembershipProvider">
      <providers>
        <clear />
        <!--<add name="UmbracoMembershipProvider" type="Umbraco.Web.Security.Providers.MembersMembershipProvider, Umbraco" minRequiredNonalphanumericCharacters="0" minRequiredPasswordLength="10" useLegacyEncoding="false" enablePasswordRetrieval="false" enablePasswordReset="false" requiresQuestionAndAnswer="false" defaultMemberTypeAlias="Member" passwordFormat="Hashed" allowManuallyChangingPassword="false" requiresUniqueEmail="false" />-->
        <add name="UsersMembershipProvider" type="Umbraco.Web.Security.Providers.UsersMembershipProvider, Umbraco" minRequiredNonalphanumericCharacters="0" minRequiredPasswordLength="10" useLegacyEncoding="false" enablePasswordRetrieval="false" enablePasswordReset="false" requiresQuestionAndAnswer="false" passwordFormat="Hashed" allowManuallyChangingPassword="false" requiresUniqueEmail="false" />
        <add name="MyMembersMembershipProvider" type="RB.ActiveDirectoryProviders.ActiveDirectoryUmbracoMembersMembershipProvider, RB.ActiveDirectoryProviders" connectionStringName="CicLadpConnectionString" attributeMapUsername="sAMAccountName" defaultMemberType="MemberType" />
      </providers>
</membership>

  <connectionStrings>
    <remove name="umbracoDbDSN" />    
    <add name="MyLadpConnectionString" connectionString="LDAP://DC1.xxx.xxx" />
  </connectionStrings>

There are some question,

1. The umbraco backoffice is successful running, but when I click the Members menu in the left , error occur

An error occured

Object reference not set to an instance of an object.

Exception Details

System.NullReferenceException: Object reference not set to an instance of an object. Stacktrace

at System.Object.GetType() at Umbraco.Web.Trees.ApplicationTreeExtensions.

1. Is this package possible support the "Public access" provided by Umbraco ? If yes, how can I do that ? Thanks

Thanks
