I have a web application that uses AzMan authorization to grant different functionality to different users. I've just started using WatiN to implement some automated web UI tests that run under Visual Studio Team System/TFS. I'd like to be able to use it to verify the different authorization scenarios. To do this though I'd need to be able to run different tests as different users who are granted differing rights through AzMan (using dummy test accounts).
Does anyone have experience with automating testing of AzMan authorization?
How about running VS "unit" tests as different users under TFS?
