[Samba] Samba 3.4.2 Winbind problem IDMAP GID range full

[Greg]

I updated my smb.conf to include the following parameters:
[global]
   idmap backend = tdb
   idmap alloc backend = tdb
   idmap uid = 10000-11000
   idmap gid = 10000-11000
   winbind enum users = yes
   winbind enum groups = yes

This seems to have fixed some of the errors, but I still get the following
errors in log.winbindd-idmap (repeated many times):
[2009/12/08 16:41:48,  0] winbindd/idmap_tdb.c:341(idmap_tdb_alloc_init)

I tried with and without the backend parameters getting the same result. I'm
not sure if those or the 'enum' parameters are necessary. FWIW, there exitst
a file /var/lib/samba/winbindd_idmap.tdb but the timestamp on it is over two
years ago.
