FAST Search Server 2010 Wizard : Username or domain is incorrect
When implementing a new product, you're bound to stumble on new issues (or at least I thought it was an issue). I had installed FAST Search Server 2010 for SharePoint on a dedicated server. Everything went fine until I wanted to follow the configuration wizard for FAST Search Server. When I wanted to enter the user name and password in the dialog box, I received a "User name or domain is incorrect." error.
Let's say our domain was named domain.local. Using these formats gave us an error:
DOMAIN\fast_service
fast_service@domain.local
After I was searching for an hour what the problem could be, the customer himself apparently succeeded in getting through the configuration wizard by using this format:
domain.local\fast_service
In Microsoft products - including SharePoint 2010 - I never had to use this use name format. It are the little things...
