BUG: SQLOLEDB Provider Ignores or Removes Trailing Spaces from Password on the Connection Open Method
This article was previously published under Q304310
If a Microsoft SQL Server password includes trailing
spaces, the OLE DB Provider for SQL Server (SQLOLEDB) ignores or removes those
spaces before it passes the credentials to the backend server. In addition, you
receive the following error message:
Run-time error
'-2147217843(80040e4d)':
Login failed for user 'UserName'.
This
problem does not occur with OLE DB Provider for ODBC Drivers.
To work around this problem, use the OLE DB Provider for
ODBC Driver instead of the OLE DB Provider for SQL Server, or do not create
passwords with trailing spaces.
Microsoft has confirmed that this is a bug in the Microsoft
products that are listed at the beginning of this article.
Steps to Reproduce Behavior
- Open a new Standard EXE project in Microsoft Visual Basic
6.0. Form1 is created by default.
- Set a reference to Microsoft ActiveX Data Objects
2.X.
- Copy and paste the following code into the code window of
Form1:
Note You must change User ID=<UID> and
password=<strong password> to the correct values before you run this
code. Make sure that <UID> has the appropriate permissions to
perform this operation on the database.
Private Sub Form_Load()
Dim cn As New Connection
Dim cn2 As New Connection
Dim cn3 As New Connection
cn.Open "Provider=sqloledb;Data source=scout333;" & _
"User ID=<UID>;Password=<strong password>;initial catalog=northwind"
On Error Resume Next
cn.Execute "sp_revokedbaccess 'User1'"
cn.Execute "sp_droplogin 'User1'"
On Error GoTo 0
cn.Execute "sp_addlogin 'User1', 'Test ', 'Northwind'"
cn.Execute "sp_adduser 'User1', 'User1'"
cn2.Open "Provider=MSDASQL;Driver=sql server;" & _
"server=scout333;UID=User1;PWD=Test ;"
MsgBox "Connection State: " & cn2.State
cn3.Open "Provider=sqloledb;Data source=scout333;" & _
"User ID=User1;Password=Test ;"
End Sub
- Be sure to change the connection string for the cn object so it correctly uses an existing SQL Server log on. Also,
change the connection strings for the cn2 and cn3 objects so they correctly point to your SQL Server.
- Run the code. When the connection that uses the OLE DB
Provider for ODBC Drivers connects, you receive confirmation of this connection
in a message box. This message box contains a connection state of 1 (adStateOpen) if the connection is made properly.
- Click OK in the message box. The code attempts to make the connection by
using the OLE DB Provider for SQL Server. This fails with the above-mentioned
error message.
