Hi.

Since the introduction of libcapng support and particularly after this commit:
66bd5dd32836a770647b8acf3476fb7922be71eb
gnome-keyrin-daemon is broken on OpenBSD.

The reason is that we do not support filesystem capabilities, so the
daemon is installed setuid root. However with the aforementioned commit,
the drop_privileges() function got removed so the daemon does not drop
its privileges back to the calling user. Then of course, DBus refuses the
connection to the user socket.
At least that's how I analyze it (I may have overlooked something).

For now, I've removed the setuid bit from gnome-keyring-daemon and it seems
to work fine (side note: we do not use the PAM module either).

I'm not providing a patch because I'm not sure what your preferred solution
would be in that case, but if you have any input I'll be glad to provide
you with one.
Thanks.
