WCF托管在IIS中，与集成安全性连接到数据库的问题

Question

我在开发XP计算机上有IIS 5.1中托管的WCF服务。该服务无法使用Integrated Security = True连接到SQL Server DB。在控制台应用程序中托管时，同一服务正常。我没有选中匿名访问权限，并检查了IIS中的集成Windows身份验证

这些是我在web.config中的设置

 <connectionStrings>
 <add name="CADISEntities"  connectionString="metadata=res://*/UDI.CADISEntities.csdl|res://*/UDI.CADISEntities.ssdl|res://*/UDI.CADISEntities.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=DBSQLP404;Initial Catalog=CadisCustom;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
 </connectionStrings>

我尝试将集成安全性更改为SSPI和可信连接=是，但没有运气。以下是配置设置。

  <service behaviorConfiguration="CADISBehaviour" name="GlobalInvestors.FIPA.BLL.UDI.CADISSecurities">
    <endpoint binding="basicHttpBinding" bindingConfiguration="CADISBinding"
      contract="GlobalInvestors.FIPA.BLL.UDI.ICADISSecurities" />
  </service>

  <basicHttpBinding>
    <binding name="CADISBinding" closeTimeout="01:30:00" openTimeout="01:30:00"
      receiveTimeout="01:30:00" sendTimeout="01:30:00" maxBufferSize="65536000"
      maxBufferPoolSize="52428800" maxReceivedMessageSize="65536000">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Ntlm" proxyCredentialType="Ntlm" />
      </security>
    </binding>
 </basicHttpBinding>

和客户

  <endpoint address="http://ainaost4.amerus.corp.tld/FIPA/BLLHost/CADIS.svc"
    behaviorConfiguration="Behavior" binding="basicHttpBinding"
    bindingConfiguration="BasicHttpBinding_ICADISSecurities" contract="CADISEntities.ICADISSecurities"
    name="BasicHttpBinding_ICADISSecurities">
    <!--<identity>
      <userPrincipalName value="AINAOST4\ASPNET" />
    </identity>-->
  </endpoint>

    <binding name="BasicHttpBinding_ICADISSecurities" closeTimeout="01:30:00"
      openTimeout="01:30:00" receiveTimeout="01:30:00" sendTimeout="01:30:00"
      allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
      maxBufferSize="655360000" maxBufferPoolSize="655360000" maxReceivedMessageSize="655360000"
      messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
      useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Ntlm" proxyCredentialType="Ntlm"
          realm="" />
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
    </binding>

没有在代码中设置模仿我得到的”基础提供商未能开放“在代码中设置模仿，我得到”无法初始化SSPI"

 [OperationBehavior(Impersonation = ImpersonationOption.Required)]

尝试谷歌搜索，发现无法在IIS 5.1中设置应用程序池。

任何解决问题的建议都将不胜感激。
