[Samba] Samba 3.4.2 Winbind problem IDMAP GID range full

[Greg]

I was finally able to resolve these error messages. I was missing the
winbind settings in /etc/nsswitch.conf:
   passwd:         compat winbind
   group:          compat winbind
This is in addition to the settings that I had made to /etc/samba/smb.conf:
   idmap backend = tdb
   idmap alloc backend = tdb
   idmap uid = 10000-11000
   idmap gid = 10000-11000
   winbind enum users = yes
   winbind enum groups = yes
