I can not seem to get sql server to recognize my credentials.
Asp.net recognizes me when I login but when I execute a sql command I get a login failed message.
The IIS server and SQL server are on different machines.
There are other applications the IIS server which are able to authenticate to the sql server. I believe the Active Directory settings are correct. I am investigating what I am doing differently.
I must be missing something.
- I check the IIS settings
- The web config is set to impersonate.
Below is the relevant information. If anyone has any idea as to what I missed or am doing wrong I would appreciate some help.
IIS Settings:
- 'Integrated Windows authentication' is checked
- 'Enable anonymous access" is not checked
Web Config
<authentication mode="Windows"/>
<identity impersonate="true"/>
<authorization>
<deny users="?" />
</authorization>
Page_Load Code:
Dim winId As IIdentity = HttpContext.Current.User.Identity
TextBoxMessage.Text = winId.Name + Environment.NewLine
Dim cnn As SqlClient.SqlConnection
Try
Dim sql As String = "*****"
cnn = New SqlClient.SqlConnection("Data Source=*****;Initial Catalog=****;Integrated Security=True")
cnn.Open()
Dim cmd As New SqlClient.SqlCommand(sql, cnn)
cmd.ExecuteNonQuery()
cnn.Close()
Catch ex As Exception
TextBoxMessage.Text += ex.Message
cnn.Close()
End Try
Output:
Domain\UserName
Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
