I have an app that is being developed for our Intranet.
I have it so it will authenticate users that are members in an Active directory group.
But I am running into a problem when they try to connect to the SQL server.
Instead of connecting based on the Windows group, it is still connecting as NT AUTHORITY\ANONYMOUS .
How can i get the SQL connection to use the Windows group?
here is the Web.config:

<configuration>
<system.web>
<authentication mode= "Forms">
<forms loginUrl="Webform2.aspx" name="adAuthCookie" timeout="60" path="/" >
</forms>
</authentication>
<authorization>
<allow users="*" />
<deny users="?" />
</authorization>
<identity impersonate="true" />
</system.web>
</configuration>

Here is my connection string
"workstation id=5WQ1K81;packet size=4096;integrated security=SSPI;data source=SERVERNAME;persist security info=False;initial catalog=livedb"

I setup a Windows group on the Database and in Active Directory.

The exception from SQL is
System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

Let me know if you need more details.
