samba - Jun 2002 - wbinfo returns subset of all the users (stale data?)

I am gradually learning winbindd here, and i think I have some stale 
user entries showing up.  How do I clean this up / reset this?

I dutifully added a credentialed user via 
wbinfo -A 'administrator%passwd' 

Now  RestrictAnonymous = 1 does not stop wbinfo -u from working, but I
get a small (6/)subset of users back.  What gives?  How do I reset
this?  

[root@array22 source]# wbinfo -u
GENEARRAY+allan
GENEARRAY+garoot
GENEARRAY+Guest
GENEARRAY+IUSR_ARRAY13
GENEARRAY+IWAM_ARRAY13
GENEARRAY+wynston

[root@array22 source]# wbinfo -t
Secret is good
[root@array22 source]# 

I know I'm missing something here - 

Thanks

Oh yes.. version 2.2.5 of samba, connecting to a Win2k PDC- SP2.

Just to show that I am trying on my own here.. I see that the 
users are saved in winbindd_cache.tdb  - so I need to update that file -
correct?
