I have tested the changed using test domain, it is working as per the expectation.

Just some thoughts on this from my perspective.

<PROTOCOL>.domain was a quick fix to get things working when I first did this. Which was not done consistently as outlined in all the patches.

I'm also not sure about the fallback to server when domain is not available in some cases where I use IP's for servers to get through proxies this could create issues.

I don't think the global property domain is the right way to deal with this long term. My thinking was to at some point require the domain of a user be included as a column of the users.csv. This allows more flexibility with multi domain testing and associates the domain more directly with where it is needed the user.

All the code would need to be updated to support users.csv driven domains consistently then remove the domain property setting.
