Make pdb_ads survive a restart of Samba4
The search function retries once, the modifying call that hits a dead smbd
returns an error. The next try will reconnect. This was simple to implement and
provides a good compromise against Samba4 idling our connection. Most of the
modifying calls are quickly after a search (like OpenUser) anyway.
