I can connect to a Teradata db instance using a DSN entry. When I reference that same DSN entry in an adodb connection string the .Open command generates the error "Not enough information to log on"
Dim conn As New ADODB.Connection
conn.ConnectionString = "DSN=TDFADS_SYS"
conn.Open
Debug.Print Err.Description ' returns: [Teradata][ODBC Teradata Driver] Not enough information to log on
I've also created a connection string that bypasses the DSN (references ODBC directly) but the error is still generated.
conn.ConnectionString = "DRIVER=Teradata;UID=;AUTHENTICATION=;USEINTEGRATEDSECURITY=Y;DBCNAME=tdfadscop1.gsm1900.org"' not enough info
conn.Open
Debug.Print Err.Description ' returns: [Teradata][ODBC Teradata Driver] Not enough information to log on
The DSN entry is defined to use integrated security. I believe adodb isn't passing this information on to the db instance which then causes the connection to fail.
Does anyone have an example of an vba adodb connection string that works with Integrated Security?
Thanks in advance.
