NULL realm is no realm. thus you check with unlang as to whether is a realm.

my previous answer already did that.

please stop thkining about DEFALT and NULL anyway - those things are going - think instead of
what the realm looks like, what format it is and how you want it handled (you shouldnt be using
DEFAULT either ;-) )
