Issue: When recording with WPM, the website Windows authentication works. But when deployed, it does not and the page returns "not authorized" page.
Resolution: You may need to set up domain user worker accounts, as the local SEUM-User-# accounts might not have access to the page in question, especially if you are using Windows authentication.
If you are on the latest version of WPM, there is a domain agent configuration utility that makes this process fairly easy. You will need two Active Directory accounts for this, so you can either use existing users or create two new domain 'worker' accounts. Make sure you can log into the Player server as those users and can access the page in a browser successfully.
The utility is found at C:\Program Files (x86)\SolarWinds\Orion\SEUM\Player\SolarWinds.SEUM.AgentDomainConfigurationTool.exe.
