Hi,
I've just implemented my first application onto a test web server.
When the code comes to creating a connection object it throws an error
saying the "Login failed for user '(null)'. Reason : Not associated with a
trusted connection".
I'm using integrated security and it works from the IIS server I have set up
on my local machine. The connection string I'm using is
strCN = "data source='DIVCS-SQL2\SQL2K';Tru sted_Connection =true;initial
catalog=Helpdes kDevelopment;Us er Id='" & objCurrentUser. Name & "'"
Where objCurrentUser is a WindowsIdentity object. This object is returning
the correct username.
I've done everything according to the book (ASP.NET unleashed) and I've
checked the knowledge base.
Thanks in advance....Paul 2 1629
With a trusted connection, you don't need to pass the User Id ... it will
use the current windows user credentials. In ASP.NET, this is typically the
asp worker process account. Does this account have access to your
helpdeskdevelop ment database? If not, it will need access and you'll need
to handle any extra security with custom login forms and back-end tables.
If you need to impersonate a windows user and use windows security instead,
you'll need to setup web.config correctly.
See http://msdn.microsoft.com/library/de...tionSchema.asp
with particular attention to the <authentication >, <authorization> , and
<identity> elements.
Hope that helps.

Hi Paul,
Asp.net applications run under local windows aspnet account.
Thus, trusted connections will
a) ignore User Id
b) use aspnet account to log in to sql server.
You have at least tow options at this point:
a) run your app under different windows account (that is trusted to sql
server)
Example:
Just put a line into web.config file somewhere under
<system.web> node:
<identity impersonate="tr ue" userName="USER" password="PASSW ORD"/>
b) use sql server authentication

Hi and thanks in advance!
I have an Access 2000 front end and a SQL Server 2000 back end. When
the Access main form opens I run code that logs the user on to the SQL
server using the generic read only log on I have created. On some PCs
I am having a problem. The code runs and then displays a Log On box
with the Trusted Connection checked and the users NT logon displayed.
What causes this? Is there a way to correct it?
Thanks!

Hi folks,
Just want to make sure I've got this right.
I've got an application I want to authenticate to the domain i.e. an

everythings tickety boo) and I can get the username and various other bits
