Teradata studio connection to mds : Could not log on user - response (2) by fgrimmer

From looking at the log, it looks like the first attempt to logon fails wihout a user name or password, but then it succeeds after that. So trying to find out what was done by the user at that point. What is the sequence of events you have done within Studio? What objects are you trying to show in the Interdependency Browser? Are you invoking from the 'Show Interdependecies' menu option from the Data Source Explorer or from the toolbar in the Teradata View?  Also, what Web Server have you deployed the MDS Web Service in?
