No idea, but I'd recommend strace'ing logind when this happens, and
tracking looking for relevant operations on the device nodes...

logind doesn't do anything particularly magic... We just invoke
libacl, and normally libacl should validate enough what we pass
there...

do you use any MAC or so? selinux? smack? apparmor?

Do you any non-standard UIDs? i.e. 65535 or so?
