That does sound the same as my case.  I'm going to do some more
experimentation.  wbinfo queries winbind directly, bypassing NSS which
should help point point where it is failing.

I'm also going to look into mitigating it with hooks in Network
Manager/systemd which "knows" what connections are up and running. 
Restarting winbind on a laptop is quick and wont disturb anyone else.
