I think the xdm-config file got overwritten during the port upgrade with the
default (secure?) settings. I had to comment out the last setting in xdm-config

% tail -3 /usr/local/lib/X11/xdm/xdm-config
! SECURITY: do not listen for XDMCP or Chooser requests
! Comment out this line if you want to manage X terminals with xdm
!DisplayManager.requestPort:    0
% 

now seems to be working fine.
