SharePoint表单认证问题 急求！！！
网上找了很多文章，现在的问题是用域帐号可以登录站点并且给sql 用户授权。但是授权的sql用户不能登录站点，提示没有权限。而且有点用户用权限检查也可以检查到权限。 以下是配置文件， 我只定义了membershipprovider 没有定义rolemanager. 之前写过一个简单的membershipprovider 的代码只重写了两个方法，还可以授权并且登录，现在却不知道什么问题

 <membership defaultProvider="i">
      <providers>
        <add name="i" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthMembershipProvider, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
  <add connectionStringName="connectionString" applicationName="/" name="SAPProvider" type="MemberShipProviderForSAP.SAPProvider,MemberShipProviderForSAP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=5c4da3b74518c687" />
      </providers>
    </membership>
    <roleManager defaultProvider="c" enabled="true" cacheRolesInCookie="false">
      <providers>
  <clear/>
        <add name="c" type="Microsoft.SharePoint.Administration.Claims.SPClaimsAuthRoleProvider, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" />
      </providers>
    </roleManager>
  </system.web>
<connectionStrings>
<add connectionString="Server=localhost;Database=xxxDB;Integrated Security=true" name="connectionString" providerName="System.Data.SqlClient" />
<!--<add connectionString="Server=localhost;Database=aspnetdb;Integrated Security=true" name="MyAspNetDB" providerName="System.Data.SqlClient" />-->
</connectionStrings>
