wbinfo -u/-g should work if the configuration is correct. At least they 
work for me on 3.5.4. What are your idmap settings?

For me, getent group works but not getent passwd. However, id does work 
for mapped accounts.

You might want to look in/tail log.winbindd, log.winbindd-idmap and see 
what is going on when you issue a winbind -u/-g.
