I followed that lead, and found that no SPN were registered at all in

I looked at other objects an dit seems none have had the same SPN
registered, and I don't know at all how the object is created (other
that it is created when I "realm" the server). I will look at it a bit
There is an issue if realmd uses adcli to join the domain if 'hostname'
only returns the short name and not the fully-qualified DNS name. In
this case adcli tries to add the same SPN twice which causes an error
and as a result no SPN is added.
