To my knowledge the Samba Team is aware of the issue already. Basically it is a scalability issue with the design of winbindd (basically winbindd is single threaded and blocks on large requests). BTW: 'getent passwd' works flawlessly on the tested system as the number of presented entries is rather low and can be handled from the cache.
