WCF 托管在 IIS 中，连接到具有集成安全性的数据库时出现问题
我的 XP 开发计算机上有一个托管在 IIS 5.1 中的 WCF 服务。该服务无法连接到集成安全性=true 的 SQL Server 数据库。当托管在控制台应用程序中时，相同的服务可以正常工作。我未选中匿名访问并检查了 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="Data Source=DBSQLP404;Initial Catalog=CadisCustom;Integrated Security=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
</connectionStrings>
我尝试更改为 SSPI 的集成安全性和可信连接 = 是，但没有运气。下面是配置设置。
<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>
在客户端中，
<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>
如果没有在代码中设置模拟，我会得到“底层提供程序在打开时失败”，在代码中设置模拟，我会得到“无法初始化 SSPI”
[OperationBehavior(Impersonation = ImpersonationOption.Required)]
尝试谷歌搜索并发现无法在 IIS 5.1 中设置应用程序池。
任何解决该问题的建议将不胜感激。
I have a WCF service hosted in IIS 5.1 on my development XP machine. The service cannot connect to sql server DB with integrated security=true. The same service works fine when hosted in a console app. I have unchecked Anonymous access and checked the Integrated Windows Authentication in IIS
These are my setting in Web.Config
<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="Data Source=DBSQLP404;Initial Catalog=CadisCustom;Integrated Security=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
</connectionStrings>
I have tried changing to Integrated security to SSPI and Trusted Connection =Yes, but no luck. Below is the Config settings.
<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>
and in client
<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>
Without setting Impersonation in the code I get "The underlying provider failed on Open" setting Impersonation in the code and I get "Cannot Initialize SSPI"
[OperationBehavior(Impersonation = ImpersonationOption.Required)]
Tried googling and found that Application pool cannot be set in IIS 5.1.
Any suggestion to fix the issue would be greatly appreciated.

通过在连接字符串中提供完全限定的 sql server 名称解决了该问题
fixed the issue by giving fully qualified sql server name in the connection string
