It would probably be good to take this conversation about EXTERNAL to a
bug, as well, to stop bothering other list members (it can be the same
bug). When you do, please attach your generated config.h, or at least
the lines mentioning DBUS_BUS_ENABLE_KQUEUE, HAVE_ADT, HAVE_CMSGCRED,
HAVE_GETPEEREID, HAVE_GETPEERUCRED, HAVE_UNPCBID and
HAVE_UNIX_FD_PASSING - those are all interesting facts for one of the
issues you've mentioned in this thread.

It will be if you stop patching dbus to not force EXTERNAL-only. Sorry,
I should have been more specific about testing with upstream D-Bus
(modulo any patches that are strictly necessary for other reasons, like
the one for broken poll()), and not with your vendor patchset.

The hard-coded default, if there are no <auth> directives, is that all
supported authentication mechanisms are attempted; that's currently
EXTERNAL, DBUS_COOKIE_SHA1 and ANONYMOUS, except that ANONYMOUS fails by
default and must be enabled separately (for obvious reasons). If there
are <auth> directives, only those authentication mechanisms will be tried.

*Something* is demonstrating to the dbus-daemon's satisfaction that your
uid is 505, but I can't tell yet whether it's EXTERNAL (prove your uid
by AF_UNIX credentials-passing) or DBUS_COOKIE_SHA1 (prove your uid by
creating files in ~/.dbus-keyrings with specified contents).
