SYMPTOMS

Some providers may receive an incorrect password value from the OLEDB32 component. This behavior occurs if the password in the connection string is blank in Windows 7 or in Windows Server 2008 R2.

This issue affects the providers that meet both of the following conditions:
  • The provider does not support COM aggregation.
  • The provider uses an empty string (VT_BSTR L””) as the default value for OLE DB property DBPROP_AUTH_PASSWORD.
For example, when you provide a blank password in the following connection string to the provider, the provider receives lots of junk instead of a null value when password is passed into the provider.

Server = localhost; Data Source = SomeCatalog ; User Id = ; Password = ;
