The plot thickens, I am testing using an Oracle VM with a bridged 
adapter, which can connect to either wifi or ethernet. Whilst doing 
further testing I just discovered something. If I logon as a domain user 
with the bridged adapter connected to wifi (wlan0), the user gets logged 
in. If I then log out and switch the bridged adapter to eth0 with the 
cable disconnected, the user can still logon and quickly. However if the 
cable isn't disconnected, then the user can still logon, but after a 
considerable amount of time and there is a similar pause when the user 
logs out.

I am surmising that the pause is coming from something searching for the 
network and then, finally, giving up.

Now to try and find the 'something' and stop it doing it.
