Player map visibility is indeed a server difficulty setting. And players are definitely grouped when the mission starts.
However, it's possible that after dying and respawning, players are no longer grouped, which could explain why nobody was seeing group map markers. I'll test this theory.
I've tracked down the real issue, which is that only the team leader class is given a GPS. Giving every player a GPS allows everyone to see player markers on the map.
As of b0332ba411189dc46939cb162f7de43cfac8984e, players cannot see each their teammates marked on the map. Although this may have something to do with the difficulty settings, player markers were visible in other missions with that same difficulty on the same server.
