[Samba] Trouble using winbind: getent not returning all groups

[Larry]

I am running samba 3.0.22 on a solaris10 server currently running in a 
NT 4.0 Domain.
I have successfully joined the domain.
wbinfo -u successfully returns all my NT users
wbinfo -g will give me all my NT groups.
getent passwd will successfully return all my NT users with uid's etc.
getent group returns only the first 50 or so NT groups.

It doesn't seem to log any errors in the logs.

Anyone have any ideas?
