I did. My Gentoo samba service scripts starts smbd and nmbd. Oh. Ugh. 
Sorry. Found an untweaked option in the samba service script 
configuration file--that I had apparently known about while setting up 
the AD DC--which was necessary to start winbindd. It's now running, and 
the wbinfo and getent utilities are now behaving better:

     terra ~ # wbinfo --ping-dc
     checking the NETLOGON for domain[HOME] dc connection to 
"ceres.home.graham-family.org" succeeded
terra ~ # getent passwd SAMDOM\\jgraham 
HOME\jgraham:*:10000:11001::/home/jgraham:/bin/bash

Thanks; fixed.

I've been following the Samba Member Server Troubleshooting wiki page 
and have resolved almost everything. The only thing I've got at the 
moment that's undiagnosed is getting the domain join to be completely 
clean:

terra ~ # net ads leave -U Administrator Deleted account for 'TERRA' in 
realm 'SAMDOM.EXAMPLE.COM terra ~ # net ads join -U Administrator Using 
short domain name -- SAMDOM Joined 'TERRA' to dns domain 
'samdom.example.com' DNS Update for terra.samdom.example.com failed: 
ERROR_DNS_UPDATE_FAILED DNS update failed: NT_STATUS_UNSUCCESSFUL

/var/log/samba/log.winbindd shows:

My /etc/hosts is, I think, exactly correct:

127.0.0.1 localhost ::1 localhost

(Note that this machine uses dhcpcd to get its IP address and the 
contents of /etc/resolv.conf.)
