I know this is a bit of an edge case but I want to be sure I'm not missing something....
Customer wishes to install Ent Reporter 3.0 in AD Domain B.
Domain B doesn't contain any SQL servers.
Customer has a SQL server in Domain A and wants to have Reporter send data to the database using SQL Authentication.
There is no trust between Domain A and Domain B.
Now here's the interesting bit... based on testing in my lab, I was able to create the Reporter DB on the Domain A SQL Server by referencing a SQL login contained therein.
However, there doesn't appear to be any way to use the same approach to have the Discovery Cluster / nodes submit data to the database?
The dialog for setting up the cluster / nodes has a check box that is supposed to allow use of different credentials for "SQL authentication". I believe the dialog is using this term a bit loosely and really means specifying alternative domain credentials for accessing SQL.
