Force MS Access ODBC Connection to use SQL Server Authentication - sql-server

Question

I'm using the following code that is run from my Autoexec macro to make the ODBC connection.
'Name : CreateDSNConnection
'Purpose : Create a DSN to link tables to SQL Server
'Parameters
' sServer: Name of SQL Server that you are linking to
' sDatabase: Name of the SQL Server database that you are linking to
' sUsername: Name of the SQL Server user who can connect to SQL Server, leave blank to use a Trusted Connection
' sPassword: SQL Server user password
Public Function CreateDSNConnection(sServer As String, sDatabase As String, sUsername As String, sPassword As String) As Boolean
Dim sConnect As String
On Error GoTo CreateDSNConnection_Err
If Len(sUsername) = 0 Then
'//Use trusted authentication if stUsername is not supplied.
sConnect = "Description=DBTraining" & vbCr & "SERVER=" & sServer & vbCr & "DATABASE=" & sDatabase & vbCr & "Trusted_Connection=Yes"
Else
sConnect = "Description=DBTraining" & vbCr & "SERVER=" & sServer & vbCr & "DATABASE=" & sDatabase
End If
DBEngine.RegisterDatabase "DBTraining", "SQL Server", True, sConnect
'Add error checking.
CreateDSNConnection = True
Debug.Print "Connection made"
Exit Function
CreateDSNConnection_Err:
CreateDSNConnection = False
MsgBox "CreateDSNConnection encountered an unexpected error: " & Err.Description, vbCritical, "Unexpected Error!"
End Function
Pretty standard stuff...but it seems that the ODBC connection is always setup as using Windows auth and I need it setup to use SQL Server auth. I've tried dropping in the UID= and PWD=, but it still tries to use Windows.

Answer 1

Here is a trusted connection from Access to SQL Server:
strConnectString = "Driver={SQL Server};" & _
"Server=" & strDSN & ";" & _
"Database=" & strDatabase & ";" & _
"Trusted_Connection=yes"
Or for SQL Server Authentication:
strConnectString = "Driver={SQL Server};" & _
"Server=" & strDSN & ";" & _
"Database=" & strDatabase & ";" & _
"User Id=,myUID>;Password=<MyPWD>"

Answer 2

What ended up working for me was starting it over from scratch.
I blew out the existing UserDSN from the ODBC connection.
Then opened my DB and ran the CreateDSNConnection code
That put the UserDSN back in, and was set to use SQL Server Authentication, but was using my Windows login
Deleted all linked tables and views
Recreated the links for tables and views using the Generic SQL login account and checked the Save password option
Compacted & Repaired
Sent to a user to test...it worked
I had tried every one of these steps multiple times...except for the first one. I'm guessing that there was something corrupted in the UserDSN file??? I have no idea. But deleting it and starting over completely resolved the issue.

Dim CurConn As ADODB.Connection
Set CurConn = New ADODB.Connection
CurConn.Open "Provider=myProvider;" & _
"Server=myServer;" & _
"Database=myDatabase;" & _
"Trusted_Connection=no;" & _
"User Id=myUsername;" & _
"Password=myPassword;"
This, how I do it in Access VBA.
