I'm trying to let my users connect to OLAP cube in SSAS 2005 using Excel 2007 over the Internet.
I've set up dynamic security using fact table in cube. It uses UserName function, so users should authenticate to SSAS using windows accounts. I've set up msmdpump.dll component on IIS, allowing windows authentication, but not anonimous one. I created windows accounts on web/SSAS server for remote users. My users' machines are out of my control, I can not use pass-through windows authentication.
Now, if I create connection in Excel and save username and password in it, everything works. But I want users to download Excel file without embedded credentials from my web site, and than be able to enter their credentials. Best option is if they will enter password when opening Excel file.
Problem is as soon as I clear checkbox "save password" in connection properties, or remove "User ID"/"Password" properties from connection string, Excel gives me authentication error and does not save connection properties. So I cannot create a template document or connection file without embedded credentials.
Moreover, I suspect, Excel will not ask user for login/password anyway.
Do you know a solution to my problem? Maybe some workarounds/alternative ways? I appreciate any help.
