Have you tried to configure a Microsoft Dynamics Business Central 2019 Spring release (BC14) RTM with LoginName authentication, just to find that it did not work?
You are right.
You won’t be able to login to the Web- or Windows-client and will get errors in your event log like these:

Part of the story is that the same setup simply works with earlier versions, and that Windows-authentication also works without any glitches.
At least the fix is simple: Upgrade your platform to Cumulative Update 1 (or actually I recommend the latest while you are at it anyway 🙂 ).
Note, the error is also mentioned on forum.mibuso.com here!
Thanks goes to Christoph Bendixen and Jesper Dahl Fredriksen from team.blue aka ScanNet.dk for helping reporting and identifying this problem.
