Tobias Kortkamp <t at tobik.me> has asked x11 at FreeBSD.org for maintainer-approval:
Bug 211624: x11/xdm: Use MIT-MAGIC-COOKIE-1 by default

--- Description ---
xdm has issues on FreeBSD in the default configuration.  I've had errors where
I was successfully logged in and then my X session died immediately.  With
xdm's default config SDL2 clients cannot be run, quitting with:

XDM authorization key matches an existing client!

There are other related issues (see linked bugs).  All of these issues seem to
boil down to XDM-AUTHORIZATION-1 being broken.	Adding 

DisplayManager.*.authName:     MIT-MAGIC-COOKIE-1

in xdm-config solves all of these problems.  I would like to see this in xdm in
the default configuration.

OpenBSD has done this since OpenBSD 2.4:
