Those cmsxrootd-site[1-3].fnal.gov > are connected with our dCache and EOS XROOTD doors. Is fnal eos still the 4.12 based one? Maybe there was a bug with -m support there. And maybe the same is true for the dCache doors? I remember 4.12 has some serious trouble parsing certs with DNs containing ',' ... and maybe some other characters (took me a long while t ofigure out why UCSD xcache wasn't able to auth to fnal eos :) ). I'd try to figure out the lowest level where the -m/-d problem appears. Is it on cmsxrootd-site[123].fnal.gov:1094 redirs? What versions are those? But if there is a problem with the underlying servers (dCache & EOS doors) this should really be fixed there.
